- Built high-performance REST APIs in Python and FastAPI to serve real-time product data to the browser extension and mobile app.

- Worked within a ~10-engineer team, integrating third-party data providers (Bright Data, Oxylabs, Keepa, BlueCart) and managing persistence across PostgreSQL, Redis, and Qdrant on AWS.
