AI-Augmented Development Process

Four-phase approach combining human architectural judgment with AI acceleration

1

Architecture Design (Human-Led)

Analysis of requirements, service evaluation, and architectural decisions

Strategic Decisions:

  • Requirements analysis: monitor 7k events, identify failures
  • Service evaluation: Functions vs App Service, SQL vs NoSQL
  • Architectural decisions: serverless, managed identity, test-driven approach

AI Support:

  • Generated comparison tables (Table Storage vs SQL)
  • Provided cost analysis data
  • Offered architectural pattern options
Key Insight: AI provided analysis and comparisons; human judgment drove architectural decisions based on business requirements.
2

Test-Driven Infrastructure (AI-Accelerated)

Generated 5 test functions to validate each infrastructure layer before production deployment

Traditional Approach:

  • Day 1-3: Write all functions
  • Day 4: Deploy everything
  • Day 4-7: Debug simultaneously
  • Problem: Too many variables to isolate issues

AI-Augmented Approach:

  • Day 1: Design test strategy with AI
  • Day 1: Generate 5 test functions (AI writes boilerplate)
  • Day 2: Deploy tests sequentially, AI helps debug each
  • Result: Production deployment with confidence
3

Iterative Debugging (AI as Partner)

Rapid troubleshooting with AI assistance for common cloud infrastructure issues

Bug #1: RBAC Permission Issue 5 min vs 2 hours traditional

Error: "Forbidden: The user does not have permission to perform this action"

Solution: AI identified missing "Key Vault Secrets User" role assignment

Command: az role assignment create --role "Key Vault Secrets User"

Bug #2: GraphQL Syntax Error 5 min vs 3 hours traditional

Error: 400 Bad Request on GraphQL query

Solution: AI caught incorrect field name: timeGt should be lastUpdatedTimeGt

Impact: Immediate fix vs hours of API documentation reading

Bug #3: None Type Handling 30 min vs 4 hours traditional

Error: TypeError when concatenating strings with None values

Solution: AI suggested defensive pattern: str(event.get('field') or '')

Impact: Applied pattern across entire codebase, preventing future errors

Code Quality Improvements (AI as Reviewer)

Iterative refactoring to improve maintainability and follow DRY principles

After initial generation, collaborated with AI on multiple refinement rounds:

  • Round 1: AI generates basic structure
  • Round 2: Add inline comments explaining security considerations
  • Round 3: Refactor to use environment variables instead of hardcoded values
  • Round 4: Extract reusable functions (DRY principle)
  • Result: Production-ready code with confidence

Real AI Collaboration Examples

Actual conversation patterns demonstrating effective AI collaboration

Architecture Decision: Storage Selection
Engineer
Compare Azure Table Storage vs Azure SQL for 7k events/day with append-only writes, simple queries by date range, and cost optimization
AI

Comparison:

  • Table Storage: $0.07/GB, 20k ops/sec, no schema
  • SQL: $15/GB minimum, complex queries not needed, schema rigidity

Recommendation: Table Storage for this use case

Decision: Table Storage (200x cheaper, simpler for use case)
Debugging: RBAC Permission Fix
Error Log: "Forbidden: The user does not have permission to perform this action"
Engineer
Function 2 failed with 'Forbidden' when accessing Key Vault. Using managed identity. Here's the code: [paste]
AI
The managed identity needs the 'Key Vault Secrets User' RBAC role. Run:
az role assignment create --role "Key Vault Secrets User" --assignee [identity] --scope [vault-id]
Result: Fixed in 5 minutes (vs 2 hours traditional debugging)
Code Generation: Test Function
Engineer
Create an Azure Function that tests KeyVault access:
  • Timer trigger every 15 minutes
  • Use DefaultAzureCredential (managed identity)
  • Read secret named in env var VENDOR_CLIENT_ID_SECRET_NAME
  • Log first 5 chars only for security
  • Wrap in try/except with clear error logging
  • Include inline comments
AI
[Generates 40 lines of production-ready code in 10 seconds]
Result: Human reviewed logic, AI handled syntax/boilerplate

Code Examples & Refactoring

Refactoring for Maintainability

Extracted token acquisition into reusable function following DRY principles

Before (AI's First Generation)
# Functional but verbose
def collect_data():
    credential = DefaultAzureCredential()
    kv_client = SecretClient(vault_url=..., credential=credential)
    client_id = kv_client.get_secret("VendorClientId").value
    client_secret = kv_client.get_secret("VendorClientSecret").value

    response = requests.post(
        f"{api_url}/client_token",
        json={"client_id": client_id, "client_secret": client_secret}
    )
    token = response.json()["access_token"]

    # ... 50 more lines of similar code
After (Iterative Refinement)
# Extracted reusable function
def get_vendor_token():
    """Acquire Vendor API token using KeyVault credentials"""
    credential = DefaultAzureCredential()
    kv_client = SecretClient(vault_url=..., credential=credential)
    client_id = kv_client.get_secret("VendorClientId").value
    client_secret = kv_client.get_secret("VendorClientSecret").value

    response = requests.post(
        f"{api_url}/client_token",
        json={"client_id": client_id, "client_secret": client_secret}
    )
    return response.json()["access_token"]

def collect_data():
    token = get_vendor_token()  # Now reusable
    # ... focus on data collection logic
Improvement: DRY principle applied, better maintainability, function now reusable across codebase

Defensive Coding Pattern

AI suggested pattern to prevent None type errors from Table Storage

Before (Caused TypeError)
# Error: TypeError when field is None
error_msg = event.get('field') + ' text'
After (Defensive with Fallback)
# Handles None gracefully
error_msg = str(event.get('field') or '') + ' text'
Impact: Applied pattern across entire codebase (600+ lines modified), preventing future None errors

Managed Identity Pattern

Zero secrets architecture using Azure Managed Identity

from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient

# No passwords, Azure handles authentication automatically
credential = DefaultAzureCredential()
kv_client = SecretClient(vault_url=vault_url, credential=credential)

# Retrieve secrets without managing credentials
secret_value = kv_client.get_secret(secret_name).value
Security Benefit: Zero hardcoded secrets, automatic credential rotation, RBAC-controlled access

Key Techniques for Effective AI Collaboration

1

Be Specific in Prompts

❌ Vague:

"Make a monitoring system"

βœ… Specific:

"Create an Azure Function (Python 3.11) that:

  • Timer trigger: 0 0 * * * * (hourly)
  • Authenticates to Vendor API using KeyVault credentials
  • Executes this GraphQL query: [paste query]
  • Handles pagination (100 events/page)
  • Writes to Table Storage with PartitionKey=objectType
  • Includes error handling for None values
  • Logs: 'Stored X new, Y updated'"
2

Provide Context

❌ No Context:

"This code has an error"

βœ… With Context:

"Azure Function failing with 'Forbidden' error when accessing Key Vault.

  • Environment: Python 3.11, Azure Functions v4
  • Authentication: System-assigned managed identity (enabled)
  • Code: [paste relevant section]
  • Error log: [paste full traceback]
  • What RBAC role is missing?"
3

Iterate, Don't Accept First Output

Round 1: AI generates basic structure
Round 2: "Add inline comments explaining security considerations"
Round 3: "Refactor to use environment variables instead of hardcoded URLs"
Result: Production-ready code after 3 iterations
4

Use AI for Different Roles

AI as Architect:

"Compare serverless vs VM-based for scheduled workloads under 1 hour/day"

AI as Developer:

"Generate this function based on these requirements: [spec]"

AI as Debugger:

"Here's an error, here's my code, what's wrong?"

AI as Reviewer:

"Review this code for security issues, None handling, and error logging"

AI as Documentation Writer:

"Document this function with docstrings and inline comments"

Lessons Learned

What Worked Well

  • βœ…
    Specific prompts with context

    Detailed requirements yielded better code quality

  • βœ…
    Iterative refinement

    2-3 rounds improved quality dramatically

  • βœ…
    AI as debugger

    Saved massive time on RBAC and API errors

  • βœ…
    Code generation for boilerplate

    10x faster than manual coding

  • βœ…
    Documentation writing

    AI-generated docs were surprisingly comprehensive

What Needs Improvement

  • ⚠️
    AI hallucinates APIs sometimes

    Always verify against actual documentation

  • ⚠️
    First output rarely production-ready

    Expect 2-3 iterations minimum

  • ⚠️
    Context limits

    Long conversations lose earlier context

  • ⚠️
    Security defaults

    AI might suggest less secure options first

What AI Couldn't Do (Human Skills Required)

  • 🧠
    Architecture Decisions

    AI provided comparison data, but strategic decisions on serverless vs VM, Table Storage vs SQL required business context and judgment

  • 🧠
    Requirements Analysis

    AI can't interview stakeholders or understand business context like "consecutive failures" as key metric vs any single failure

  • 🧠
    Security Design

    AI suggested options, but enforcing managed identity, RBAC least privilege, and zero secrets policy required security expertise

  • 🧠
    Strategic Thinking

    Modular test-driven approach was human design; AI implemented it but didn't suggest the strategy

Best Practices Developed

  1. Test AI suggestions in isolated functions first

    Validate each component before integration

  2. Always verify external API syntax against actual docs

    AI can hallucinate field names and endpoints

  3. Use AI for code, human for architecture

    Clear separation of concerns maximizes both strengths

  4. Iterate 2-3 times minimum before deploying

    First output is starting point, not final product

  5. Document AI interactions for future reference

    Successful prompts become reusable templates

Strategic Collaboration, Not Delegation
