A small, event-driven full-stack project inspired by travel deal monitoring: React + TypeScript frontend, Node.js + TypeScript backend, and an AWS Lambda worker that processes deal checks via SQS and sends alerts via SNS.

• Separate frontend and backend
• Event-driven pipeline: API → SQS → Lambda → SNS
• Postgres persistence for watch rules and price snapshots
• CI/CD (GitHub Actions) for lint/typecheck/tests + deployment

[Frontend (React)] | | REST v [Backend API (Node/TS)] ---> [SQS Queue] ---> [Lambda Worker (TS)] ---> [SNS Topic] ---> Email | | | v +-----> [Postgres] <--- writes snapshots + rules

• docker compose up -d (Postgres)
• npm install
• npm run dev

Scaffolding and tooling setup complete. Next: API endpoints + worker pipeline.
