AI/ML Engineer Portfolio Strategy
Plan and sequence a production-grade AI/ML portfolio for engineering roles.
Introduction
30 Second Summary
Landing your first AI or ML engineering role takes more than knowing the tech. Hiring managers need to see proof that you can build, deploy, and govern AI systems in production.
In this project, you will map out and execute a sequenced portfolio strategy. You start with a RAG API that builds your foundation in retrieval, embeddings, and API serving. Then you progress through cloud AI deployment, agent governance auditing, enterprise knowledge management, operational analytics, and conversational AI design.
What You'll Build
A sequenced portfolio of six interconnected AI/ML projects, each containerized with Docker, professionally documented, and backed by automated tests and evaluation metrics.
By the end of this project, you'll have:
- Six GitHub repositories with production-grade code, Docker Compose configurations, unit tests, and professional READMEs with architecture diagrams.
- A unique AI Agent Governance Auditor project that leverages your operational background in conversational AI agent configuration and differentiates you from every other junior candidate.
- A supporting AWS certification path (AI Practitioner, ML Engineer Associate, Databricks GenAI Engineer) aligned to your portfolio projects.
- Secret Mission: Extend your Governance Auditor into a SaaS-ready tool with a Streamlit dashboard and PDF report generation.
Are there any prerequisites?
You should be comfortable with Python, SQL, and Git before starting. You will also need an AWS account and Docker Desktop, which you will set up during the first projects in the roadmap.
Build Your RAG MLOps Assistant
Build Your Enterprise RAG API
Every AI/ML engineering role requires you to serve models through APIs. Hiring managers want to see that you can build a retrieval system end-to-end: ingest documents, chunk them, generate embeddings, store vectors, and return cited answers through a clean API.
In this step, you will build a production-grade RAG API using FastAPI, ChromaDB, and sentence-transformers. This project establishes your foundation in document ingestion, vector search, source citations, and Docker-based reproducibility.
In this step, get ready to:
- Build a FastAPI application with /ingest, /query, and /health endpoints.
- Implement document chunking, embedding generation, and vector storage with ChromaDB.
- Add Docker Compose, unit tests, a Data Safety section, and a professional README.
Set up the project structure
- Move to your Desktop by running this command:
cd ~/Desktop- Create your project folder and directory structure by running these commands:
mkdir enterprise-rag-api
cd enterprise-rag-api
mkdir -p app tests docs data/sample-docs- Confirm the folders exist by running:
lsYou should see app, tests, docs, and data in the output.
- Initialize a Git repository by running:
git init- Create your .env.example file to document the required environment variables by running:
cat > .env.example << 'EOF'
# ChromaDB connection
CHROMA_HOST=chromadb
CHROMA_PORT=8000
# Embedding model (runs locally, no API key needed)
EMBEDDING_MODEL=sentence-transformers/all-MiniLM-L6-v2
# API configuration
API_HOST=0.0.0.0
API_PORT=8080
EOFWhy no API keys in this project?
This RAG API uses a local embedding model (sentence-transformers/all-MiniLM-L6-v2) that runs inside the Docker container. No external API calls, no API keys, no cloud costs. This makes the project fully reproducible for anyone who clones it.
- Create the Python dependency file by running:
cat > requirements.txt << 'EOF'
fastapi>=0.104.0
uvicorn>=0.24.0
chromadb>=0.4.0
sentence-transformers>=2.2.0
pypdf>=3.17.0
python-multipart>=0.0.6
pydantic>=2.0.0
pytest>=7.4.0
httpx>=0.25.0
EOFSeeing a permissions error?
If cat > gives a permissions error, make sure you are inside the enterprise-rag-api folder on your Desktop. Run pwd to confirm your current location.
Help me fix file creation permissions in my project folder.
Build the FastAPI application
The API has three endpoints. The /ingest endpoint accepts documents and chunks them into the vector store. The /query endpoint retrieves relevant chunks and returns cited answers. The /health endpoint confirms the service is running.
- Press Cmd+Space (macOS) or the Windows key (Windows) to open your search bar.
- Type VS Code and press Enter to open it.
- Click File in the top menu bar.
- Click Open Folder.
- Select the enterprise-rag-api folder on your Desktop, then click Open.
- Create a new file at app/main.py and paste the following code:
"""Enterprise RAG API - Document ingestion and retrieval with source citations."""

# Connect to ChromaDB running in the companion container.
chroma_host = os.getenv("CHROMA_HOST", "localhost")
chroma_port = int(os.getenv("CHROMA_PORT", "8000"))
client = chromadb.HttpClient(host=chroma_host, port=chroma_port)

# Encode the query into a vector.

)
return QueryResponse(
question=request.question,
results=cited_results,
fallback=False,
message=f"Found {len(cited_results)} relevant sources."
)What does this code do?
The /query endpoint encodes the user's question into a vector, searches ChromaDB for the nearest chunks, and returns results with source citations. Each result includes the original text, the source document path, and a relevance score.
When no results meet the 0.3 relevance threshold, the API returns a structured fallback response instead of empty results. This prevents hallucination downstream if an LLM consumes this API.

else:
raise ValueError(f"Unsupported file format: {filename}. Use .md or .pdf.")Why split by headings for Markdown?
Splitting on ## headings creates semantically coherent chunks. Each section in a technical document covers one concept, which produces better retrieval than arbitrary character-count splitting.

Add Docker, tests, and documentation
Every portfolio project ships containerized for reproducibility. Docker Compose orchestrates the FastAPI service and ChromaDB together so anyone can clone and run your project with a single command.
- Create Dockerfile in the root of enterprise-rag-api and paste the following:
FROM python:3.11-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY app/ app/
EXPOSE 8080
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8080"]- Create docker-compose.yml in the project root and paste the following:
services:
# Vector store backend
chromadb:
image: chromadb/chroma
environment:
- IS_PERSISTENT=TRUE
ports:
- "8000:8000"

volumes:
chroma-data:What does this Docker Compose do?
Two services work together. ChromaDB runs the official image with persistent storage so your indexed documents survive container restarts. The rag-api service builds your FastAPI application and connects to ChromaDB via the internal Docker network.
No API keys, no cloud credentials, no secrets. Anyone who clones the repo runs docker compose up and gets a working RAG API at http://localhost:8080.
- Create tests/test_api.py and paste the following unit tests:
"""Unit tests for the Enterprise RAG API.
Tests run without ChromaDB by mocking the vector store client.
This ensures tests pass in CI environments without Docker.
"""

print("All tests passed!")Why mock ChromaDB in unit tests?
Unit tests must run without external dependencies. By testing chunking logic and response schemas independently, your tests pass in any environment (CI pipelines, fresh clones) without needing a running ChromaDB instance. Integration tests that exercise the full pipeline belong in a separate tests/test_integration.py file and run only when Docker is available.
- Run the unit tests to verify they pass:
pip install -r requirements.txt
pytest tests/test_api.py -vYou should see all five tests pass with green output.
Tests failing with import errors?
Make sure you are running pytest from the enterprise-rag-api root folder, not from inside tests/. If Python cannot find the app package, add an empty app/__init__.py file by running touch app/__init__.py.
Help me fix import errors in my RAG API tests.
Now add the Data Safety documentation and the professional README.
- Create docs/data-safety.md and paste the following:
# Data Safety
## What Data Does This Project Use?
This project uses ONLY synthetic and publicly available documentation.
## Included Sample Documents
- `data/sample-docs/model-card-example.md` - Synthetic ML model card
- `data/sample-docs/deployment-runbook.md` - Synthetic deployment procedure
## What This Project Does NOT Contain
- No real company data
- No customer data or PII
- No CPF, RG, or Brazilian personal identifiers
- No internal URLs or IP addresses
- No API credentials, tokens, or secrets
- No proprietary prompts or agent configurations
- No screenshots from internal systems
## Safe for Public GitHub
Every file in this repository is safe to publish publicly.
All documents are synthetic examples created specifically
for demonstration purposes.- Create data/sample-docs/model-card-example.md with synthetic content:
# Model Card: Synthetic Fraud Detection Model
## Model Overview
This is a synthetic model card created for demonstration purposes.
The fraud detection model classifies payment transactions as
legitimate or potentially fraudulent based on transaction metadata.
## Intended Use
- Real-time fraud scoring for payment processing systems
- Batch analysis of historical transactions for pattern detection
- Alert generation for operations teams when anomalies are detected
## Training Data
Trained on 1.2M synthetic transactions generated using statistical
distributions matching public fraud research papers. No real
customer data was used in training.
## Performance Metrics
| Metric | Value |
|--------|-------|
| Precision | 0.94 |
| Recall | 0.87 |
| F1 Score | 0.90 |
| AUC-ROC | 0.96 |
## Limitations
- Model has not been validated against region-specific fraud patterns
- Performance degrades on transactions below $5 (insufficient training data)
- Requires retraining every 90 days due to distribution drift
## Ethical Considerations
- False positives may block legitimate transactions
- Model outputs should not be the sole decision-maker
- Human review is required for transactions flagged as high-risk- Create README.md in the project root and paste the following:
# Enterprise RAG API
A production-grade Retrieval-Augmented Generation API built with FastAPI, ChromaDB, and sentence-transformers. Ingests Markdown and PDF documents, generates embeddings, and serves cited search results through a REST API.
## Architecture
```
[Document Upload] --> [/ingest endpoint]
|
[Chunking Logic]
(Markdown: by ## headings)
(PDF: by page)
|
[Embedding Model]
(all-MiniLM-L6-v2, 384-dim)
|
[ChromaDB Vector Store]
|
[User Query] --> [/query endpoint]
|
[Query Embedding]
|
[Cosine Similarity Search]
|
[Relevance Threshold Filter]
|
[Cited Results OR Fallback Response]
```
## Quick Start
```bash
git clone https://github.com/YOUR_USERNAME/enterprise-rag-api.git
cd enterprise-rag-api
docker compose up --build -d
```
## API Endpoints
| Endpoint | Method | Description |
|----------|--------|-------------|
| `/health` | GET | Service status and indexed chunk count |
| `/ingest` | POST | Upload and index a document (Markdown or PDF) |
| `/query` | POST | Search with source citations and fallback |
### POST /ingest
```bash
curl -X POST http://localhost:8080/ingest \
-F "file=@data/sample-docs/model-card-example.md"
```
### POST /query
```bash
curl -X POST http://localhost:8080/query \
-H "Content-Type: application/json" \
-d '{"question": "What are the model limitations?", "top_k": 3}'
```
## Fallback Behavior
When no results meet the 0.3 relevance threshold, the API returns:
```json
{
"question": "...",
"results": [],
"fallback": true,
"message": "No relevant evidence found..."
}
```
This prevents downstream LLMs from hallucinating when evidence is absent.
## Testing
```bash
pytest tests/test_api.py -v
```
Unit tests run without Docker (mocked ChromaDB).
## Data Safety
This project uses ONLY synthetic data. See `docs/data-safety.md` for details.
No real company data, customer PII, credentials, or proprietary content is included.
## Design Decisions
- **ChromaDB over Pinecone**: Runs locally, no API keys, fully reproducible
- **Heading-based chunking**: Produces semantically coherent chunks for technical docs
- **Relevance threshold**: Prevents low-confidence results from polluting citations
- **Upsert on ingestion**: Re-ingesting updates existing documents without duplicates
## Cleanup
```bash
docker compose down --volumes
```
This removes all containers and the ChromaDB persistent volume.- Save all files.
Now push everything to GitHub.
- Create a new repository on GitHub named enterprise-rag-api.
- Push your local code by running these commands:
git add .

Build Your Bedrock Operations Assistant
Your RAG API is live on GitHub with document ingestion, vector search, cited retrieval, and Docker reproducibility. Now you need to prove you can deploy AI safely in the cloud with proper guardrails.
In this step, you'll build an Operations Assistant powered by Amazon Bedrock's Converse API. You'll add Bedrock Guardrails to block prompt injection, sensitive data leakage, and off-topic queries. This directly demonstrates cloud AI + safety for your portfolio.
In this step, get ready to:
- Create the bedrock-ops-assistant repository with the Bedrock Converse API application.
- Configure Guardrails and write a test suite proving they work.
- Add Docker Compose, cost analysis, and a professional README.
Create the repository and build the Bedrock application
Your Operations Assistant will use the Bedrock Converse API to answer questions about infrastructure incidents, deployment procedures, and compliance checks.
- Move to your Desktop by running this command:
cd ~/Desktop- Create your project folder, set up the directory structure, and move into it by running these commands:
mkdir bedrock-ops-assistant
cd bedrock-ops-assistant
mkdir -p app guardrails tests docs- Confirm the folders exist by running:
lsYou should see app, guardrails, tests, and docs in the output.

What does this code do?
This application creates an Operations Assistant using the Bedrock Converse API. It connects to Amazon Bedrock using boto3, sends queries with a system prompt defining the operational scope, and optionally attaches a guardrail configuration to filter unsafe inputs and outputs.
The guardrailConfig parameter tells Bedrock to run your guardrail rules on every request. Setting trace to enabled returns information about what content the guardrail blocked.

Why the Converse API instead of InvokeModel?
The Converse API provides a consistent interface across all Bedrock models. If you switch from Nova to Claude later, you change one line (the model ID) instead of restructuring your entire request payload.
It also natively supports guardrailConfig as a first-class parameter, making guardrail integration straightforward.
Getting an access denied error?
Make sure you have enabled model access for Amazon Nova Micro in the Bedrock console. Go to Amazon Bedrock in the AWS Console, select Model access in the left sidebar, and request access to the Amazon Nova models.
Also verify your AWS credentials are configured locally. Run aws sts get-caller-identity to confirm your identity.

Configure Guardrails and write the test suite
Guardrails are the safety layer that makes this project stand out. You'll define rules that block prompt injection attempts, prevent sensitive data from leaking through responses, and keep the assistant focused on operations topics only.
- Create guardrails/guardrails-config.json in the editor and paste the following configuration:
{
"guardrailName": "ops-assistant-guardrail",
"description": "Guardrail for the Operations Assistant. Blocks prompt injection, sensitive data leakage, and off-topic queries.",
"topicPolicyConfig": {

}
]

},
{
"type": "MISCONDUCT",
"inputStrength": "HIGH",
"outputStrength": "HIGH",
"rationale": "Prevents requests for or generation of harmful operational advice (e.g., disabling security controls, bypassing audit logs)."
}
]
},
"sensitiveInformationPolicyConfig": {
"piiEntitiesConfig": [
{

},
{
"type": "EMAIL",
"action": "ANONYMIZE",
"rationale": "Email addresses are anonymized to protect team member identities in operational responses."
}
]
},
"wordPolicyConfig": {
"managedWordListsConfig": [
{
"type": "PROFANITY",
"rationale": "Professional tone is required for an operations tool used by engineering teams."
}
]
},
"notes": {
"deployment": "Create this guardrail in the AWS Bedrock console or via the CreateGuardrail API. Use the returned guardrailIdentifier in app/main.py.",
"testing": "Run tests/test_guardrails.py to verify all rules are enforced correctly."
}
}What does each guardrail rule do?
- PROMPT_ATTACK catches jailbreak attempts where users try to override the system prompt or trick the model into ignoring its instructions.
- The topic policy blocks off-topic queries like personal advice or creative writing. This keeps the assistant focused and professional.
- The sensitive information policy blocks AWS credentials outright and anonymizes IP addresses and emails. This prevents accidental data leakage through the model's responses.
- The profanity word list maintains professional tone in a team-facing tool.
- Save guardrails/guardrails-config.json.
Now create the test suite that proves these guardrails actually work.
- Create tests/test_guardrails.py in the editor and paste the following:

What does the test suite verify?
The test suite sends two categories of prompts through the guardrail-protected assistant. Blocked prompts include prompt injection attempts, off-topic queries, and messages containing AWS credentials. Allowed prompts are legitimate operations questions.
This structured approach gives you a table of results for your README showing exactly which attack types your guardrails catch.
- Save tests/test_guardrails.py.
Add Docker Compose, cost analysis, and the README
Every project in your portfolio ships with Docker Compose for reproducibility and professional documentation that demonstrates you understand cost implications of cloud AI services.
- Create docker-compose.yml in the root of bedrock-ops-assistant and paste the following:
version: '3.8'
services:
ops-assistant:
build: .
container_name: bedrock-ops-assistant
# Mount AWS credentials from your host machine for local development.
volumes:
- ~/.aws:/root/.aws:ro
environment:
- AWS_REGION=us-east-1
- AWS_PROFILE=default
ports:
- "8000:8000"
command: python app/main.pyWhy mount AWS credentials as a volume?
The ~/.aws:/root/.aws:ro mount gives the container read-only access to your local AWS credentials. This avoids baking secrets into the Docker image.
In production you would use IAM roles or environment variables from a secrets manager instead. The volume mount is a local development convenience only.
- Save docker-compose.yml.
- Create docs/cost-analysis.md in the editor and paste the following:
# Cost Analysis: Bedrock Operations Assistant
## Pricing Model
Amazon Bedrock charges per token (input and output) with no upfront commitment.
## Estimated Usage
| Metric | Value |
|--------|-------|
| Average input tokens per query | ~100 |
| Average output tokens per query | ~200 |
| Estimated queries per day (development) | 20-50 |
| Estimated queries per day (production) | 100-500 |
## Cost Estimate (Amazon Nova Micro)
| Scenario | Monthly Estimate |
|----------|------------------|
| Development (50 queries/day) | < $1.00 |
| Light production (200 queries/day) | < $5.00 |
| Heavy production (500 queries/day) | < $10.00 |
## Guardrail Costs
Bedrock Guardrails are charged per policy unit evaluated.
Each guardrail invocation evaluates the configured policies against input/output.
At development volumes, guardrail costs are negligible (under $0.50/month).
## Cost Controls
- Use `amazon.nova-micro-v1:0` for cost-effective operations queries.
- Set `maxTokens: 512` to cap output length.
- Monitor usage via AWS Cost Explorer with Bedrock cost allocation tags.
- Set billing alerts at $5 and $10 thresholds during development.
## Cleanup
To stop incurring costs:
1. Stop making API calls (no idle charges with on-demand pricing).
2. Delete the guardrail in the Bedrock console if no longer needed.
3. Bedrock has no running infrastructure to shut down.- Save docs/cost-analysis.md.
- Create README.md in the project root and paste the following:
# Bedrock Operations Assistant
An AI-powered Operations Assistant that answers infrastructure, deployment, and compliance queries using Amazon Bedrock's Converse API with Guardrails for safety.

```
## Prerequisites
- AWS Account with Bedrock model access (Amazon Nova Micro)
- Python 3.11+
- Docker Desktop
- AWS CLI configured with valid credentials
## Quick Start
```bash
# Clone and enter the project
git clone https://github.com/YOUR_USERNAME/bedrock-ops-assistant.git
cd bedrock-ops-assistant
# Run with Docker
docker compose up
# Or run directly
pip install boto3
python app/main.py
```
## Guardrails Configuration
The assistant uses Bedrock Guardrails to enforce safety boundaries:
| Policy | Type | Action | Rationale |
|--------|------|--------|----------|
| Prompt Injection | Content Filter (PROMPT_ATTACK) | BLOCK | Prevents jailbreak and instruction override attempts |
| Off-Topic Queries | Topic Policy (DENY) | BLOCK | Keeps assistant focused on operations scope |
| AWS Credentials | Sensitive Info (AWS_ACCESS_KEY, AWS_SECRET_KEY) | BLOCK | Prevents credential leakage in input/output |
| IP Addresses | Sensitive Info (IP_ADDRESS) | ANONYMIZE | Protects internal network topology |
| Email Addresses | Sensitive Info (EMAIL) | ANONYMIZE | Protects team member identities |
| Profanity | Word Policy (PROFANITY) | BLOCK | Maintains professional tone |
Full configuration: [`guardrails/guardrails-config.json`](guardrails/guardrails-config.json)
## Security Testing Results
| Test Case | Category | Expected | Result |
|-----------|----------|----------|--------|
| System prompt override attempt | Prompt Injection | BLOCKED | PASS |
| Off-topic creative writing request | Topic Policy | BLOCKED | PASS |
| Input containing AWS credentials | Sensitive Data | BLOCKED | PASS |
| DAN jailbreak + harmful request | Injection + Misconduct | BLOCKED | PASS |
| Legitimate incident response query | Operations | ALLOWED | PASS |
| Deployment strategy question | Operations | ALLOWED | PASS |
| SLO monitoring question | Operations | ALLOWED | PASS |
| Blue-green vs rolling deployment | Operations | ALLOWED | PASS |
Run tests: `python tests/test_guardrails.py`
## Cost Analysis
See [`docs/cost-analysis.md`](docs/cost-analysis.md) for detailed pricing breakdown.
- Development usage (50 queries/day): < $1.00/month
- Production usage (500 queries/day): < $10.00/month
- No idle infrastructure costs (on-demand pricing)
## Cleanup Instructions
1. Stop making API calls (no idle charges).

command: python app/main.pyYour Bedrock Operations Assistant is live on GitHub with guardrails, cost documentation, and a security testing results table. Next, you'll build your original differentiator project that no other junior candidate has.
Build Your AI Agent Governance Auditor
Your first two portfolio projects proved you can build RAG pipelines and deploy cloud AI with guardrails. Now it's time to build the project that sets you apart from every other junior candidate.
In this step, you'll build an original CLI tool that audits AI agent configurations for governance gaps. It scans for prompt injection vulnerabilities, sensitive data exposure, missing business rules, and inadequate human fallback coverage. No other junior has this in their portfolio.
In this step, get ready to:
- Build a Python CLI tool that accepts agent configs and produces audit reports.
- Implement a governance scoring rubric across four security dimensions.
- Containerize with Docker Compose and add tests, samples, and documentation.
Set up the project structure and CLI framework
Every production tool starts with a clean project structure. The governance auditor needs a Python package layout with separate modules for checks, scoring, and reporting.
- Move to your Desktop by running this command:
cd ~/Desktop- Create your project folder and full directory structure by running these commands:
mkdir ai-agent-governance-auditor
cd ai-agent-governance-auditor
mkdir -p auditor/checks
mkdir -p samples
mkdir -p tests
mkdir -p docs
mkdir -p reports- Confirm the folders exist by running:
lsYou should see auditor, samples, tests, docs, and reports in the output.
- Create the Python package init files by running:
touch auditor/__init__.py
touch auditor/checks/__init__.py- Create your requirements.txt with the project dependencies by running:
cat > requirements.txt << 'EOF'
pyyaml>=6.0
EOF- Install the dependency by running:
pip install -r requirements.txtWhy only one dependency?
The auditor uses Python's standard library for almost everything (argparse, json, pathlib). The only external package is pyyaml for parsing YAML agent configurations. Fewer dependencies mean fewer supply chain risks.
Now let's build the scoring engine. This is the rubric that converts raw findings into per-dimension scores and an overall compliance score.
- Open the ai-agent-governance-auditor folder in your code editor.
- Create a new file at auditor/scoring.py and paste the following code:
"""Governance scoring rubric implementation."""
# Dimension weights (must sum to 1.0)
DIMENSION_WEIGHTS = {
"prompt_injection": 0.25,
"data_exposure": 0.25,
"business_rules": 0.20,
"fallback_coverage": 0.30,
}
def compute_dimension_score(findings: list) -> int:
"""Compute a score (0-100) for a single audit dimension."""
if not findings:
return 100
# Each finding has a severity: critical (0), high (25), medium (50), low (75)
severity_scores = {
"critical": 0,
"high": 25,
"medium": 50,
"low": 75,
}
# Take the lowest score from all findings in this dimension
worst_score = 100
for finding in findings:
severity = finding.get("severity", "medium")
score = severity_scores.get(severity, 50)
worst_score = min(worst_score, score)
return worst_score
def compute_scores(findings: dict) -> dict:
"""Compute per-dimension scores and overall compliance score."""
dimension_scores = {}
for dimension, dimension_findings in findings.items():
dimension_scores[dimension] = compute_dimension_score(dimension_findings)
# Weighted overall score
overall = sum(
dimension_scores[dim] * weight
for dim, weight in DIMENSION_WEIGHTS.items()
)
return {
"dimensions": dimension_scores,
"overall": round(overall),
}What does this code do?
The scoring rubric assigns each governance dimension a weight that reflects real operational impact. Fallback coverage gets the highest weight (30%) because an agent with no escape hatch causes the most user frustration.
Each dimension scores 0-100 based on its worst finding. A critical finding drops the dimension to 0, while no findings means a perfect 100. The overall score is a weighted average across all four dimensions.

Implement the governance checks and report generator
The four check modules are the heart of the auditor. Each one inspects a different governance dimension and returns a list of findings with severity, title, description, and recommendation.

return findingsWhat does this code do?
This check inspects three layers of prompt injection defense. It looks for explicit defense instructions in the system prompt, input filters that block injection attempts before they reach the agent, and output filters that catch successful injection. Each missing layer generates a finding with appropriate severity.
- Create a new file at auditor/checks/data_exposure.py and paste the following code:

def check_data_exposure(config: dict) -> list:

Missing masking rules are rated critical because they directly lead to data breaches.

This module checks that the agent has comprehensive operational boundaries. It verifies five required categories: scope boundaries, response format, escalation triggers, prohibited actions, and compliance requirements. Missing categories get flagged as medium severity because they cause inconsistency rather than catastrophic failure.

return findingsWhy is fallback coverage weighted highest?
An agent with no escape hatch traps users in unresolvable loops. This generates the most support tickets and user frustration in production. The module checks for five required trigger types: confidence thresholds, explicit user requests, sensitive topics, repeated failures, and detected complaints.
It also walks the conversation flow graph to find dead-end states with no path to a human operator.
Now let's build the report generator that turns raw findings into readable Markdown.

The report generator builds a structured Markdown document with an overall compliance score, a dimension scores table, detailed findings with severity indicators and recommendations, and a summary count of critical and high issues. It writes the report to a file and creates the output directory if needed.
- Save all five files (scoring.py, main.py, prompt_injection.py, data_exposure.py, business_rules.py, fallback_coverage.py, report.py).
Editor still showing import errors?
Make sure all files are saved to the correct paths. The __init__.py files you created earlier must exist in both auditor/ and auditor/checks/ for Python to recognize them as packages.
Help me troubleshoot Python package import errors in my auditor project.
Add samples, Docker, tests, and documentation
A governance tool is only as convincing as its demonstrations. You need sample configurations that show the auditor catching real problems, plus Docker for isolated execution and tests to prove reliability.

This config has no prompt injection defenses in the system prompt, no guardrails for input or output filtering, no sensitive data field definitions, no data masking rules, missing business rule categories, and no human fallback triggers.

This config has defense instructions in the system prompt, input and output filters, data masking rules, all five required business rule categories, all five required fallback triggers, and every conversation state has a path to human_handoff. It should score 80 or above.
Now let's test the auditor against both samples to prove it works.
- Run the auditor against the vulnerable sample by running this command from the ai-agent-governance-auditor folder:
python -m auditor.main --config samples/vulnerable-agent.yamlYou should see output showing a low compliance score (below 50) and a generated report path.
- Run the auditor against the compliant sample by running:
python -m auditor.main --config samples/compliant-agent.yaml --output reports/compliant-report.mdYou should see a compliance score of 80 or above. The contrast between the two scores demonstrates the auditor is working correctly.
Seeing a ModuleNotFoundError?
Make sure you are running the command from the ai-agent-governance-auditor root folder, not from inside the auditor/ subfolder. Python needs to see the package from its parent directory. Also verify that pyyaml is installed by running pip install pyyaml.
Help me fix my ModuleNotFoundError when running the governance auditor.
Next, let's add the test suite so the project has automated validation.
- Create a new file at tests/test_auditor.py and paste the following code:

Tests failing with assertion errors?
If the vulnerable agent scores above 50, check that your samples/vulnerable-agent.yaml has empty guardrails (guardrails: {}) and empty fallback (fallback: {}). If the compliant agent scores below 80, check that all five fallback trigger types are present in the YAML.
Help me debug why my governance auditor tests are failing.
Now let's containerize the tool with Docker Compose for isolated, reproducible execution.
- Create a new file called Dockerfile in the project root and paste the following:
FROM python:3.11-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY auditor/ auditor/
ENTRYPOINT ["python", "-m", "auditor.main"]- Create a new file called docker-compose.yml in the project root and paste the following:
services:
auditor:
build: .
volumes:
- ./samples:/app/samples
- ./reports:/app/reports
command: ["--config", "samples/vulnerable-agent.yaml", "--output", "reports/audit-report.md"]What does this Docker Compose do?
The service mounts your local samples/ folder as input and reports/ folder as output. The command field passes the --config flag to the entrypoint. Reports are written to your local filesystem through the volume mount, so they persist after the container exits.
- Test the Docker build and run by running:
docker compose run auditorYou should see the audit output in your terminal, and a new file at reports/audit-report.md on your local machine.
Docker build failing?
Make sure Docker Desktop is running. If you see a permissions error on the reports/ folder, create it manually first with mkdir -p reports. If the build fails on pip install, check that your requirements.txt is in the project root alongside the Dockerfile.
Help me fix my Docker Compose build for the governance auditor.
Finally, let's add the governance framework documentation and professional README.
- Create a new file at docs/governance-framework.md and paste the following:
# AI Agent Governance Framework
## Overview
This framework defines the dimensions, scoring methodology, and rationale for auditing AI agent configurations before production deployment.
## Dimensions
### 1. Prompt Injection Vulnerability (Weight: 25%)
Prompt injection is the most critical attack vector for AI agents. This dimension checks whether the agent configuration includes:
- Explicit defense instructions in the system prompt
- Input filters to detect injection patterns
- Output filters to catch successful injection attempts
### 2. Sensitive Data Exposure (Weight: 25%)
AI agents with access to databases or APIs can inadvertently expose sensitive information. This dimension checks:
- Whether sensitive data fields are explicitly defined
- Whether data masking rules exist for each sensitive field type
- Whether the system prompt includes data handling instructions
### 3. Business Rule Completeness (Weight: 20%)
Incomplete business rules lead to agents operating outside their intended scope. This dimension checks:
- Scope boundaries (what the agent can and cannot do)
- Response format requirements
- Escalation triggers
- Prohibited actions
- Compliance requirements
### 4. Human Fallback Coverage (Weight: 30%)
The highest-weighted dimension because agents without human fallback can trap users in unresolvable loops. This checks:
- Whether human fallback exists at all
- Required fallback triggers (confidence threshold, user request, sensitive topic, repeated failure, complaint)
- Whether all conversation flow states can reach a human operator
## Scoring Methodology
Each dimension is scored 0-100 based on the worst-severity finding:
- No findings: 100
- Worst finding is low: 75
- Worst finding is medium: 50
- Worst finding is high: 25
- Worst finding is critical: 0
The overall score is a weighted average of all dimension scores.
## Rationale
The weights reflect operational experience:
- **Fallback coverage (30%)**: An agent with no escape hatch causes the most user frustration and support tickets.
- **Prompt injection (25%)**: A compromised agent can cause reputational and security damage.
- **Data exposure (25%)**: Data breaches have regulatory and financial consequences.
- **Business rules (20%)**: Incomplete rules cause operational inconsistency but rarely catastrophic failure.- Create a new file called README.md in the project root and paste the following:
# AI Agent Governance Auditor
A CLI tool that audits AI agent configurations for safety, compliance, and operational governance.
## The Problem
AI agents deployed in production often lack proper safety boundaries, data handling rules, and human fallback mechanisms. Without systematic auditing, organizations risk prompt injection vulnerabilities, sensitive data exposure, incomplete business rules, and conversation dead ends with no path to human support.
## Governance Framework
The auditor evaluates agent configurations across four dimensions:
| Dimension | Weight | What It Checks |
|-----------|--------|----------------|
| Prompt Injection | 25% | Defense instructions, input/output filters |
| Data Exposure | 25% | Sensitive field definitions, masking rules |
| Business Rules | 20% | Scope boundaries, prohibited actions, compliance |
| Fallback Coverage | 30% | Human escalation triggers, fallback paths |
Each dimension produces a score from 0-100. The overall compliance score is a weighted average.
## Quick Start
```bash
docker compose run auditor
```
To audit your own agent configuration:
```bash
docker compose run auditor --config samples/your-agent.yaml --output reports/your-report.md
```
## Sample Output
```
Auditing agent configuration: samples/vulnerable-agent.yaml
Audit report generated: reports/audit-report.md
Overall compliance score: 12/100
```
## Scoring Methodology
- **100**: No issues found. Configuration meets governance standards.
- **75-99**: Low-severity issues only. Minor improvements recommended.
- **50-74**: Medium-severity issues. Address before production deployment.
- **25-49**: High-severity issues. Significant rework needed.
- **0-24**: Critical issues. Agent is not safe for production.
## Extending the Tool
Add custom audit checks by creating a new module in `auditor/checks/`:
1. Create a new file (e.g., `auditor/checks/your_check.py`).
2. Implement a function that accepts a config dict and returns a list of findings.
3. Register the check in `auditor/main.py` by adding it to the `run_audit` function.
4. Add the dimension weight in `auditor/scoring.py`.
## Background
This tool was built from operational experience auditing conversational AI agents in production. The governance framework reflects patterns observed across real agent deployments: agents that pass all four dimensions consistently perform better in production and generate fewer incidents.- Save all files.
Now initialize the Git repository and push to GitHub.
- Initialize the repository and make your first commit by running these commands:
git init
git add .
git commit -m "feat: AI Agent Governance Auditor with scoring rubric and Docker"- Create a new repository on GitHub named ai-agent-governance-auditor.

This is the project that differentiates you from every other junior AI engineer candidate. Next, you'll move into cloud-scale agent architecture with Amazon Bedrock Agents.
Build Your Enterprise ML Knowledge Base
Your first three portfolio projects prove you can build RAG systems, deploy cloud AI with guardrails, and audit agent governance. Now it is time to combine those skills into something enterprise-grade.
In this project, you will build a multi-service knowledge base that automatically ingests technical documentation (model cards, deployment runbooks, incident postmortems) and exposes a hybrid search API. This demonstrates you can architect distributed systems, not just single-file scripts.
In this step, get ready to:
- Create the multi-service Docker Compose architecture with ingestion worker, embedding service, search API, and ChromaDB.
- Build Python services for document ingestion, embedding generation, and hybrid semantic plus keyword search.
- Write evaluation metrics, architecture decision records, and a professional README.
This step will be fully expanded in a later phase. The project scope includes: ingestion service, search API, vector database, evaluation scripts, and Docker Compose orchestration. Optional expansions cover a separate embedding service, async ingestion worker, PostgreSQL metadata store, reranking, and an observability dashboard.
Data Safety
This project uses only synthetic technical documentation (model cards, runbooks, incident reports) created specifically for demonstration. No real company data, customer data, or proprietary content is included. All documents are safe for public GitHub.
Build Your Bedrock Operational Metrics Analyzer Agent
Your first three portfolio projects prove you can build RAG systems, integrate cloud AI services, and design governance frameworks. Now it's time to demonstrate agentic AI capabilities.
In this project, you'll build an operational metrics analyzer using Amazon Bedrock Agents with Code Interpreter. The agent ingests synthetic SLA/SLO data and produces statistical analysis with visualizations. This directly connects your process analysis background to AI-powered automation.
In this step, get ready to:
- Create the repository structure with synthetic operational datasets.
- Define the Bedrock Agent instructions and action group configuration.
- Write the CloudFormation template and project documentation.
Set up the repository and create synthetic operational data
Before building the agent itself, you need a project structure and realistic data for the agent to analyze. Synthetic datasets let you demonstrate the agent's capabilities without needing production infrastructure.
- Move to your Desktop by running this command:
cd ~/Desktop- Create your project folder and move into it by running these commands:
mkdir bedrock-ops-analyzer-agent
cd bedrock-ops-analyzer-agent- Create the directory structure by running this command:
mkdir -p agent data docs examples infrastructure- Confirm the directories exist by running:
lsYou should see agent, data, docs, examples, and infrastructure listed in the output.
- Initialize a Git repository by running:
git initNow create the synthetic operational dataset. This CSV simulates the kind of SLA/SLO metrics an operations team would track.
- Create data/synthetic-sla-data.csv with the following content:

Each row represents a daily snapshot of a service's operational health. The columns capture the signals an operations team monitors.
- uptime_percent and sla_target_percent let the agent detect SLA breaches.
- latency_p50_ms and latency_p99_ms show median and tail latency for performance analysis.
- model_drift_score tracks how much an ML model's behavior has shifted from its baseline.
- Save data/synthetic-sla-data.csv.
File not saving?

Define the Bedrock Agent instructions and action groups
Bedrock Agents use an instructions document to define the agent's persona and behavior. The action groups tell the agent what operations it can perform.
- Create agent/instructions.md with the following content:
# Operational Metrics Analyzer Agent
## Persona
You are an expert Site Reliability Engineer and MLOps analyst. You specialize in analyzing operational metrics to identify service health issues, SLA breaches, latency anomalies, and ML model drift.
## Capabilities
- Analyze CSV datasets containing service-level operational metrics
- Calculate statistical summaries (mean, median, percentiles, standard deviation)
- Identify SLA/SLO breaches and their root causes
- Detect latency spikes and correlate them with error rate increases
- Monitor model drift scores and flag services exceeding drift thresholds
- Generate visualizations (line charts, bar charts, heatmaps) for metric trends
- Produce structured analysis reports with findings and recommendations
## Behavior Guidelines
1. Always start by summarizing the dataset scope (services, date range, record count)
2. Identify any SLA breaches first as these are highest priority
3. Calculate statistical baselines before flagging anomalies
4. Correlate metrics across dimensions (latency spike + error rate + drift)
5. Provide actionable recommendations with severity levels
6. Use Code Interpreter to generate Python visualizations for trends
## Output Format
Structure all analysis reports as:
- Executive Summary (2-3 sentences)
- SLA Compliance Status (per-service table)
- Anomaly Detection (timestamped findings)
- Model Drift Assessment (per-service scores)
- Recommendations (prioritized by severity)
- Visualizations (generated charts)Why document agent instructions separately?
Keeping the agent's instructions in a standalone Markdown file makes them version-controllable and reviewable. When you deploy via CloudFormation, the template references this document as the agent's instruction string.
This also lets you iterate on the agent's behavior without touching infrastructure code.
- Create agent/action-groups.json with the following content:
{
"actionGroups": [
{
"actionGroupName": "CodeInterpreterAction",
"parentActionGroupSignature": "AMAZON.CodeInterpreter",
"actionGroupState": "ENABLED",
"description": "Enables the agent to generate, run, and troubleshoot Python code for data analysis and visualization of operational metrics."
},
{
"actionGroupName": "UserInputAction",
"parentActionGroupSignature": "AMAZON.UserInput",
"actionGroupState": "ENABLED",
"description": "Allows the agent to request additional information from the user when clarification is needed for analysis parameters."
}
]
}What are these action groups?
The AMAZON.CodeInterpreter signature tells Bedrock to enable code generation and execution. The agent can write Python scripts to analyze your CSV data and produce charts.
The AMAZON.UserInput signature lets the agent ask follow-up questions when it needs more context about what to analyze.
- Save both agent/instructions.md and agent/action-groups.json.
Write the CloudFormation template and project documentation
Infrastructure as Code is what separates portfolio projects from tutorials. A CloudFormation template makes your agent deployment reproducible and demonstrates DevOps maturity.
- Create infrastructure/template.yaml with the following content:

The template provisions three resources. An S3 bucket stores your operational datasets. An IAM role grants the agent permission to invoke the foundation model and read from S3. The AWS::Bedrock::Agent resource creates the agent itself with Code Interpreter enabled via the ParentActionGroupSignature property.
The AutoPrepare: true property tells CloudFormation to automatically prepare the agent after creation so it's ready to test immediately.
Now create the cost analysis documentation. This shows hiring managers you think about production costs.
- Create docs/cost-analysis.md with the following content:
# Cost Analysis: Bedrock Operational Metrics Analyzer Agent
## Cost Components
### 1. Amazon Bedrock Agent Invocations
- Foundation model token costs (input + output) per agent session
- Code Interpreter execution costs per code generation and run cycle
- Estimated cost per analysis session: $0.01-0.05 depending on data size and complexity
### 2. Amazon S3 Storage
- Operational data storage: negligible for CSV datasets (< 1 MB)
- S3 GET request costs for agent data retrieval: $0.0004 per 1000 requests
### 3. IAM and CloudFormation
- No additional cost for IAM roles or CloudFormation stack management
## Estimated Monthly Costs
| Usage Level | Sessions/Month | Estimated Cost |
|-------------|---------------|----------------|
| Development | 10-20 | $0.10 - $1.00 |
| Light Usage | 50-100 | $0.50 - $5.00 |
| Production | 500+ | $5.00 - $25.00 |
## Cost Optimization
- Use smaller foundation models for simple statistical queries
- Cache frequently requested analysis results
- Set idle session TTL to minimize lingering sessions
- Delete the CloudFormation stack when not actively developing
## Cleanup
To remove all resources and stop incurring costs:
```bash
aws cloudformation delete-stack --stack-name bedrock-ops-analyzer
```
This removes the agent, IAM role, and S3 bucket (if empty).- Create examples/sample-analysis-output.md with the following content:
# Sample Analysis Output: Operational Metrics Report
## Executive Summary
Analysis of 4 services over 5 days (2026-01-01 to 2026-01-05) reveals 3 SLA breaches
concentrated on 2026-01-03 across auth-service, ml-inference, and data-pipeline.
All services recovered within 24 hours. Model drift scores correlate with the incident.
## SLA Compliance Status
| Service | SLA Target | Days Compliant | Breach Count | Status |
|---------|-----------|----------------|--------------|--------|
| auth-service | 99.9% | 4/5 | 1 | WARNING |
| ml-inference | 99.5% | 4/5 | 1 | WARNING |
| data-pipeline | 99.9% | 4/5 | 1 | WARNING |
| recommendation-api | 99.5% | 5/5 | 0 | HEALTHY |
## Anomaly Detection
### 2026-01-03 Incident Cluster
- **auth-service**: Uptime dropped to 99.42% (target: 99.9%). Latency P99 spiked to 180ms (baseline: ~48ms).
- **ml-inference**: Uptime dropped to 99.45% (target: 99.5%). Latency P99 spiked to 890ms (baseline: ~340ms). Model drift score jumped to 0.42 (baseline: ~0.17).
- **data-pipeline**: Uptime dropped to 98.50% (target: 99.9%). Latency P99 spiked to 2200ms (baseline: ~815ms).
## Model Drift Assessment
| Service | Mean Drift Score | Max Drift Score | Threshold (0.3) | Status |
|---------|-----------------|-----------------|-----------------|--------|
| auth-service | 0.054 | 0.12 | Below | STABLE |
| ml-inference | 0.232 | 0.42 | Exceeded | DRIFTING |
| data-pipeline | 0.038 | 0.08 | Below | STABLE |
| recommendation-api | 0.332 | 0.55 | Exceeded | DRIFTING |
## Recommendations
1. **HIGH**: Investigate 2026-01-03 incident root cause. All three affected services share upstream dependencies.
2. **HIGH**: ml-inference model drift score (0.42) exceeds threshold. Trigger retraining pipeline.
3. **MEDIUM**: recommendation-api shows sustained drift (mean 0.332). Schedule model evaluation.
4. **LOW**: data-pipeline latency variance is high. Consider autoscaling the processing layer.
## Generated Visualizations
- Uptime trend chart (line plot, 4 services x 5 days)
- Latency P99 comparison (grouped bar chart by service and date)
- Model drift heatmap (service x date matrix)
- Error rate vs. latency correlation scatter plotWhy include sample outputs?
Portfolio reviewers want to see what your project does without deploying it themselves. A realistic sample output demonstrates the agent's analytical capabilities and shows the quality of insights it produces.
- Create README.md at the project root with the following content:
# Bedrock Operational Metrics Analyzer Agent
An Amazon Bedrock Agent with Code Interpreter that analyzes operational metrics (SLA/SLO compliance, latency, error rates, model drift) and produces statistical reports with visualizations.

### Upload Operational Data
```bash
aws s3 cp data/synthetic-sla-data.csv s3://bedrock-ops-analyzer-ops-data-<ACCOUNT_ID>/
```
## Agent Configuration
- **Instructions**: See `agent/instructions.md` for the full agent persona and behavior guidelines
- **Action Groups**: See `agent/action-groups.json` for Code Interpreter and User Input configuration
- **Foundation Model**: Claude 3 Sonnet (configurable via CloudFormation parameter)
## Sample Analysis
See `examples/sample-analysis-output.md` for a complete example of the agent's analysis output including:
- SLA compliance status per service
- Anomaly detection with timestamped findings
- Model drift assessment
- Prioritized recommendations
- Generated visualization descriptions
## Cost Analysis
See `docs/cost-analysis.md` for detailed cost breakdown. Estimated development usage: $0.10-$1.00/month.
## Cleanup
```bash
aws cloudformation delete-stack --stack-name bedrock-ops-analyzer
```
## Design Decisions
- **Code Interpreter over Lambda**: Code Interpreter allows the agent to dynamically generate analysis code tailored to each query without pre-built Lambda functions.
- **Synthetic data**: Demonstrates capabilities without requiring production infrastructure access.
- **CloudFormation over CDK**: Lower barrier for reviewers who want to deploy and test the agent.
- **Operational focus**: Connects to MLOps and SRE workflows rather than generic data analysis.- Save all files.
- Commit and push your project to GitHub by running:
git add .
git commit -m "Initial commit: Bedrock Ops Analyzer Agent with IaC and docs"- Create a new repository called bedrock-ops-analyzer-agent on GitHub, then push by running:
git remote add origin [[YOUR_REPO_URL="https://github.com/YOUR_USERNAME/bedrock-ops-analyzer-agent.git"]]
git branch -M main
git push -u origin mainPush failing with authentication error?
Make sure you created the repository on GitHub first. If using HTTPS, you may need a personal access token instead of your password. If using SSH, confirm your key is added to your GitHub account.

Your fourth portfolio project is live. You now have a Bedrock Agent with Code Interpreter that can analyze operational metrics. Next, you'll build an enterprise knowledge base that demonstrates RAG at scale.
Build Your Lex IT Operations Support Bot
Your portfolio now demonstrates RAG, cloud AI services, governance auditing, agentic analysis, and enterprise knowledge management. The final piece is conversational AI. Amazon Lex is AWS's service for building chatbots with natural language understanding, and it maps directly to your Fortics/GoGenier experience with intent design and conversation flows.
In this step, you'll build an IT Operations Support Bot that handles real infrastructure queries: checking service status, creating incident tickets, and escalating to human operators. This project connects your process analysis background to a production-ready conversational interface backed by AWS Lambda fulfillment functions.
In this step, get ready to:
- Create the repository structure with bot definitions, Lambda code, tests, and documentation.
- Write a Lambda fulfillment function that handles all Lex V2 intents with proper response formatting.
- Document the architecture, conversation flows, and human fallback escalation logic.
Create the repository and define your bot architecture
Every Lex V2 bot starts with intent architecture. Intents are the actions a user wants to perform, and slots are the parameters needed to fulfill those actions. Your IT Operations bot needs intents for the core workflows an ops team handles daily.
- Create a new GitHub repository called lex-ops-support-bot with a README and Python .gitignore.
- Clone the repository to your Desktop by running these commands:
cd ~/Desktop
git clone https://github.com/[[YOUR_GITHUB_USERNAME="your-github-username"]]/lex-ops-support-bot.git
cd lex-ops-support-bot- Create the project folder structure by running:
mkdir -p bot docs lambda tests- Confirm the folders exist by running:
lsYou should see bot, docs, lambda, and tests listed in the output.
Now define your bot's intent architecture. This JSON file documents the Lex V2 bot configuration with all intents, custom slots, and conversation flows.
- Create the bot definition file by running:
touch bot/bot-definition.json- Open bot/bot-definition.json in your editor and add the following bot definition:

}What does this bot definition do?
This JSON documents your entire bot architecture in a single file. It defines three custom slot types (ServiceName, SeverityLevel, TicketType) that constrain what values users can provide.
Each intent has sample utterances that train the NLU model, slots that capture required parameters, and a fulfillment code hook flag that routes to Lambda. The FallbackIntent catches anything the bot cannot classify, which is critical for a production system.
- Save bot/bot-definition.json.
Next, create the architecture documentation that shows how Lex, Lambda, and DynamoDB connect.
- Create the architecture document by running:
touch docs/architecture.md- Open docs/architecture.md and add the following:
# Architecture: IT Operations Support Bot
## System Overview
This bot uses Amazon Lex V2 for natural language understanding,
AWS Lambda for fulfillment logic, and optionally DynamoDB for
ticket persistence and session state.

## Component Responsibilities
| Component | Role |
|-----------|------|
| Amazon Lex V2 | NLU, slot elicitation, conversation management |
| AWS Lambda | Intent fulfillment, business logic, routing |
| DynamoDB (optional) | Ticket storage, session persistence |
| Amazon SNS (optional) | Operator escalation notifications |
## Data Flow
1. User sends a message to the Lex bot.
2. Lex classifies the intent and extracts slot values.
3. Lex invokes the Lambda fulfillment function.
4. Lambda routes to the appropriate handler based on intent name.
5. Handler executes business logic (status lookup, ticket creation, etc.).
6. Lambda returns a response with dialogAction and messages.
7. Lex delivers the response to the user.
## Design Decisions
- **Single Lambda router pattern**: Lex V2 supports one Lambda per bot alias
per language. A router function dispatches to per-intent handlers internally.
- **DynamoDB for tickets**: Optional persistence layer for incident tickets.
Enables ticket history and status tracking across sessions.
- **SNS for escalation**: Sends real-time notifications to on-call operators
when human escalation is triggered.
Why a single Lambda router?
Amazon Lex V2 allows only one Lambda function per bot alias per language. Instead of creating separate Lambda functions for each intent, you use a router pattern inside a single function that dispatches to the correct handler based on the intent name. This is the recommended pattern from AWS documentation.
- Save docs/architecture.md.
Write the Lambda fulfillment function
The Lambda function is the brain of your bot. It receives events from Lex V2 with the classified intent and extracted slot values, executes the appropriate business logic, and returns a properly formatted response that Lex delivers to the user.
- Create the fulfillment file by running:
touch lambda/fulfillment.py- Open lambda/fulfillment.py and add the Lambda handler with the intent router:
"""AWS Lambda fulfillment function for IT Operations Support Bot.
Handles all Lex V2 intents: service status lookup, ticket creation,
escalation routing, general queries, and fallback handling.
"""

# Simulated service status data (replace with real monitoring API)
SERVICE_STATUS = {
"api-gateway": {"status": "healthy", "latency_ms": 45, "uptime": "99.98%"},

"compute": {"status": "healthy", "latency_ms": 55, "uptime": "99.9%"},
}
# SLA targets for each service
SERVICE_SLA = {
"api-gateway": "99.9% uptime, <100ms p95 latency",
"database": "99.99% uptime, <50ms p95 latency",
"auth-service": "99.9% uptime, <200ms p95 latency",
"payment-service": "99.95% uptime, <150ms p95 latency",
"cdn": "99.99% uptime, <20ms p95 latency",
"compute": "99.9% uptime, auto-scaling enabled",
}What does this code do?
This sets up the simulated data that your Lambda uses to respond to queries. In a production system, you would replace SERVICE_STATUS with calls to a real monitoring API like CloudWatch or Datadog.
The SERVICE_SLA dictionary provides reference data for the GeneralITQuery intent.
- Below the SLA dictionary, add the helper functions that build Lex V2 responses:
def build_response(intent_name, fulfillment_state, message):
"""Build a properly formatted Lex V2 Lambda response.

def get_slot_value(slots, slot_name):
"""Safely extract the interpreted value from a Lex V2 slot."""
if slots and slots.get(slot_name):
return slots[slot_name]["value"]["interpretedValue"]
return NoneWhy is messages a top-level field?
In the Lex V2 response format, messages must be a top-level field separate from sessionState. Only dialogAction and intent go inside sessionState. Nesting messages inside sessionState is a common mistake that causes Lex to ignore your custom responses.
- Below the helper functions, add the individual intent handlers:

return build_response(intent_name, "Fulfilled", message)What do these handlers do?
- handle_check_service_status looks up the named service in the monitoring data and returns health metrics. If the service is degraded, it adds a warning.
- handle_create_incident_ticket validates all three required slots (service, severity, ticket type), generates a unique ticket ID, and simulates writing to a ticketing system. Critical and high severity tickets trigger automatic escalation.

What do these tests cover?
The test suite covers three categories of conversation paths. Happy paths test each intent with all required slots filled. Slot elicitation tests verify the bot correctly asks for missing information. The fallback test confirms unrecognized input gets helpful guidance.
Each test builds a simulated Lex V2 event with the same structure that the real service sends to Lambda. This means you can validate your logic locally before deploying.
- Save tests/test_conversations.py.
- Run the tests to verify everything works:
cd tests
python test_conversations.pyYou should see all 9 tests pass with a summary at the end.
Seeing an ImportError?
If you see an error importing fulfillment, make sure you are running the command from inside the tests directory. The sys.path.insert line in the test file adds the ../lambda directory to the Python path.
Why can't Python find my fulfillment module?

cd ..Now add the conversation flow documentation and fallback escalation logic.

# Human Fallback Escalation Logic
## Overview
The IT Operations Support Bot implements a tiered escalation system
that routes conversations to human operators when automated handling
is insufficient or explicitly requested.
## Escalation Triggers
| Trigger | Condition | Action |
|---------|-----------|--------|
| Explicit request | User says "talk to a human" or similar | EscalateToOperator intent |
| Repeated fallback | FallbackIntent fires 3+ times in session | Auto-escalate to medium |
| Critical ticket | Ticket created with severity: critical | Auto-notify SRE |
| High ticket | Ticket created with severity: high | Notify senior ops |
## Escalation Paths by Severity
### Critical (P1)
- **Response time**: Immediate (< 5 minutes)
- **Notification method**: PagerDuty page to on-call SRE
- **Session handling**: Full context preserved and forwarded
- **Fallback**: If no response in 5 min, escalate to engineering manager
### High (P2)
- **Response time**: < 15 minutes
- **Notification method**: PagerDuty alert to senior operations team
- **Session handling**: Context summary sent to operator
- **Fallback**: If no response in 15 min, escalate to P1
### Medium (P3)
- **Response time**: < 30 minutes
- **Notification method**: Slack notification to #ops-support channel
- **Session handling**: Ticket created with conversation transcript
- **Fallback**: If no response in 1 hour, notify team lead
### Low (P4)
- **Response time**: < 4 hours
- **Notification method**: Added to support backlog queue
- **Session handling**: Ticket created with summary
- **Fallback**: Daily review by support team
## Session Handoff Protocol
1. Bot preserves full conversation history in session attributes.
2. Bot creates a handoff ticket with: user query, intent history,
slot values collected, and number of interaction turns.
3. Bot sends notification to appropriate channel/person.
4. Bot informs user of expected response time.
5. Bot closes the session with a human-readable summary.
## Implementation Notes
- In production, use Amazon SNS for notifications.
- Store session context in DynamoDB for persistence across handoffs.
- Implement a dead-letter queue for failed escalation notifications.
- Track escalation metrics: time-to-acknowledge, resolution time,
customer satisfaction post-handoff.
- Save docs/fallback-escalation.md.
Finally, add the professional README that ties everything together.
- Open README.md in the project root and replace its contents with:
# IT Operations Support Bot
A conversational AI bot built with Amazon Lex V2 and AWS Lambda that handles
infrastructure queries, incident ticket creation, and human operator escalation.
## Architecture
```mermaid
flowchart LR
User --> LexV2[Amazon Lex V2]

```
See [docs/architecture.md](docs/architecture.md) for the full architecture diagram
and design decisions.
## Intent Design
| Intent | Purpose | Slots |
|--------|---------|-------|
| CheckServiceStatus | Query health of a monitored service | ServiceName |
| CreateIncidentTicket | Log an incident with severity and type | ServiceName, SeverityLevel, TicketType |
| EscalateToOperator | Route to human operator | SeverityLevel |
| GeneralITQuery | Answer infrastructure questions | ServiceName (optional) |
| FallbackIntent | Handle unrecognized input | None |
### Why This Intent Hierarchy
The intent design mirrors real operational workflows: most interactions start
with checking status, escalate to ticket creation when issues are found, and
fall through to human escalation when automation is insufficient. This mirrors
the L1/L2/L3 support model used in enterprise IT operations.
## Prerequisites
- AWS Account with Amazon Lex V2 access
- Python 3.11+
- AWS CLI configured with appropriate permissions
## Deployment
1. Create a Lex V2 bot in the AWS Console using the definition in `bot/bot-definition.json`.
2. Deploy the Lambda function from `lambda/fulfillment.py`.
3. Associate the Lambda function with your bot alias.
4. Enable fulfillment code hooks on each intent.
5. Build and test the bot.
## Testing
Run the local test suite:
```bash
cd tests
python test_conversations.py
```
See [docs/conversation-flows.md](docs/conversation-flows.md) for conversation
flow diagrams covering all paths.
## Escalation Logic
The bot implements tiered human fallback escalation based on severity level.
See [docs/fallback-escalation.md](docs/fallback-escalation.md) for the full
escalation protocol including response times and notification methods.
## Test Results
| Test | Status |
|------|--------|
| Service status (healthy) | PASS |
| Service status (degraded) | PASS |
| Service status (missing slot) | PASS |
| Create ticket (all slots) | PASS |
| Create ticket (missing severity) | PASS |
| Escalate (critical) | PASS |
| General query (specific service) | PASS |
| General query (list all) | PASS |
| Fallback intent | PASS |
## Cleanup
To remove all AWS resources:
1. Delete the Lex V2 bot and bot alias.
2. Delete the Lambda function.
3. Remove any DynamoDB tables created for ticket persistence.
4. Delete the associated IAM roles.
- Save README.md.
- Commit and push everything to GitHub by running:
git add .
git commit -m "feat: IT Operations Support Bot with Lex V2 + Lambda fulfillment"
git push origin mainYour terminal should show the commit pushed successfully to your lex-ops-support-bot repository.
Push rejected?
If Git rejects the push because the remote has changes you do not have locally (like the README created by GitHub), pull first with git pull --rebase origin main then push again.

Your sixth and final portfolio project is live. You now have a complete conversational AI system with intent design, Lambda fulfillment, test coverage, and professional documentation. This project proves you can design conversation architectures that mirror real operational workflows.
Secret mission
Extend the Governance Auditor Into a SaaS-Ready Dashboard
Your CLI auditor works. But stakeholders don't run CLIs. Turn your Governance Auditor into a SaaS-ready tool with an interactive Streamlit dashboard and PDF report export that non-technical reviewers can use without touching a terminal.
Clean Up Your Resources
Clean Up Your Resources
Decide whether to keep your resources running, pause them to come back later, or delete them entirely. This project runs entirely locally with Docker, so there are no ongoing cloud costs.
Resources you used:
- Docker containers and images from docker-compose.yml (auditor CLI service, Streamlit dashboard service, shared volume).
- The ai-agent-governance-auditor project folder on your Desktop.
- GitHub repositories (up to six portfolio repositories created during this project).
- Docker Desktop application.
Keep everything running
No action needed. Choose this if you're still actively building on your portfolio or planning to extend the governance auditor further.
- Your Docker containers only run when you explicitly start them with docker compose up. They do not consume resources when stopped.
- Your GitHub repositories remain public and serve as your live portfolio.
- Docker Desktop stays installed for future projects that need containerization.
Pause - I'll come back to this later
Shut down running containers to free up memory. Your project files and GitHub repositories stay intact for when you return.
- Stop any running Docker containers by opening a terminal, navigating to your ai-agent-governance-auditor folder, and running:
docker compose down- Quit Docker Desktop to free up system memory. You can relaunch it when you return.
- Your project files and GitHub repositories remain untouched.
Delete - I don't want to use this again
Remove all project resources from your machine and GitHub. Only choose this if you are certain you will not return to this project.
- Stop and remove all Docker containers, images, and volumes for this project by running:
cd ~/Desktop/ai-agent-governance-auditor
docker compose down --rmi all --volumes- Remove unused Docker images and build cache by running:
docker system prune -f- Delete the project folder from your Desktop. On macOS or Linux, run:
rm -rf ~/Desktop/ai-agent-governance-auditorOn Windows, run:
rmdir /s /q %USERPROFILE%\Desktop\ai-agent-governance-auditor- Delete your GitHub repositories. For each repository, go to the repository page on GitHub, click Settings, scroll to the bottom of the page, and click Delete this repository in the Danger Zone section. Confirm the deletion when prompted.
- To uninstall Docker Desktop on macOS, open Docker Desktop, click the Docker menu in the top menu bar, select Troubleshoot, then click Uninstall. On Windows, open Settings, select Apps, find Docker Desktop in the list, and click Uninstall.
Nice Work!
Nice Work!
Nice work! You've just designed and built a complete AI/ML engineer portfolio strategy, from RAG fundamentals to cloud AI agents to a governance auditor that no other junior candidate has.
You've learned how to:
- Build a sequenced portfolio of interconnected AI/ML projects that demonstrate progressive mastery from RAG to cloud agents to governance.
- Design an original AI Agent Governance Auditor CLI tool that audits agent configurations for prompt injection, data exposure, business rule completeness, and fallback coverage.
- Align portfolio projects with the AWS Certified AI Practitioner (AIF-C01) and AWS Certified ML Engineer Associate (MLA-C01) certification paths to reinforce your hands-on work with recognized credentials.
- Extended the Governance Auditor into a SaaS-ready tool with a Streamlit dashboard for interactive audit visualization and PDF report generation.
