AI Compliance Auditor for E-Commerce

• 

Inspiration

E-commerce platforms struggle with moderating millions of product reviews daily. Manual moderation is slow, expensive ($1+ per review), and inconsistent due to human bias. We saw an opportunity to leverage Amazon's latest Nova Premier AI model to create an intelligent, scalable solution that provides 99% cost savings while ensuring regulatory compliance with complete audit trails.

What it does

Our AI Compliance Auditor analyzes product reviews in real-time using Amazon Nova Premier to detect toxicity, bias, and hallucinations. It provides intelligent scoring (0-10 scale), generates contextual summaries, and applies flexible compliance policies (standard/strict/mild modes). Every decision is logged with detailed explanations for regulatory compliance, and the entire system processes reviews in 3-5 seconds with complete audit trails.

How we built it

We built a serverless architecture on AWS using:

• Amazon Bedrock Nova Premier (inference profile us.amazon.nova-premier-v1:0) for real AI analysis

• AWS Step Functions for workflow orchestration

• AWS Lambda (Python 3.12) for microservices processing

• Amazon DynamoDB for audit logs with TTL cleanup

• AWS CDK (TypeScript) for Infrastructure as Code

• API Gateway for RESTful endpoints with rate limiting

The system integrates real Bedrock Converse API calls with proper JSON parsing to handle Nova Premier's markdown-wrapped responses.

Challenges we ran into

• Bedrock Permissions: Getting the correct IAM permissions for Nova Premier inference profiles across regions took multiple iterations

• JSON Parsing: Nova Premier returns responses wrapped in markdown code blocks, requiring custom parsing logic

• Model ID Confusion: Distinguishing between foundation model IDs and inference profile IDs

• Error Handling: Implementing robust fallback mechanisms when Bedrock API calls fail

• Real-time Processing: Balancing AI analysis quality with response time requirements

Accomplishments that we're proud of

• Real AI Integration: Successfully integrated Amazon Nova Premier with production-quality error handling

• End-to-End Testing: Comprehensive validation showing different AI scores for different content types

• Production Deployment: Fully deployed system processing real reviews with 100% success rate

• Intelligent Analysis: AI provides nuanced scoring (e.g., T:2, B:1, H:5) rather than binary decisions

• Complete Audit Trail: Every AI decision logged with detailed explanations for regulatory compliance

• Flexible Compliance: Three compliance modes working correctly with same AI analysis

What we learned

• Nova Premier Capabilities: The model provides sophisticated, context-aware analysis with detailed explanations

• Serverless Scalability: AWS serverless architecture can handle unlimited scale with pay-per-use pricing

• AI Prompt Engineering: Structured prompts with clear scoring criteria produce consistent, reliable results

• Compliance Requirements: Enterprise content moderation needs complete audit trails and flexible policies

• Cost Efficiency: Real AI analysis at $0.01 per review vs $1+ for manual moderation represents transformational savings
