Receipt Intelligence Platform
National-brand infrastructure that verifies receipts in seconds, stops fraud, and returns actionable insights to marketing and finance teams.
DynamoDB + Kinesis Pipeline
Scroll to watch data flow through our event-driven architecture. Changes cascade from Lambda through DynamoDB Streams to Kinesis, fanning out to multiple processors.
Lambda mutations write to DynamoDB with idempotent upserts. DynamoDB Streams capture changes in real-time and publish to Kinesis. Multiple Lambda processors subscribe with filter parameters, enabling parallel processing of fraud detection, rewards calculation, and notifications.
AppSync API Pipeline
Client requests flow through our GraphQL gateway with JWT validation, pipeline resolvers, and Lambda orchestration.
AppSync receives GraphQL requests and routes them through pipeline resolvers. The authorizer Lambda validates JWT tokens, checks Cognito sessions, and applies adaptive MFA rules. If authorized, the API Lambda executes business logic with shared context from previous pipeline steps.
SNS + SQS Distribution
Events published to SNS topics fan out to multiple SQS queues, enabling decoupled microservice communication.
SNS topics receive events and distribute them to subscribed SQS queues with message filtering. Each queue serves a specific microservice, ensuring loose coupling and independent scaling. Lambda consumers poll queues and process messages with automatic retry and dead-letter queue handling.
Event-Driven Validation Pipeline
Each stage is isolated, observable, and designed to auto-scale during national promotions.
Mutation Lambda
Normalizes payloads, applies dedupe hashes, and writes receipts to DynamoDB.
- Idempotent upsert
- Audit logging
DynamoDB Table
Single-table schema with TTLs, GSIs, and promotion-based partitioning.
