What I'm looking for

I'm looking to build reliable backend services, APIs, and real-time products where I can own systems from design through deployment and continue growing in distributed systems.

I've delivered APIs and end-to-end integrations for 4+ client projects at FounDev Studio, improving PostgreSQL query performance from roughly 600ms to under 100ms and building reusable error-handling and logging infrastructure.

I also deployed a restaurant KOT/POS system used in production for 100+ daily orders, with real-time WebSocket synchronization below 50ms. My projects span FastAPI microservices, distributed rate limiting, JWT authentication, Redis, MongoDB, PostgreSQL, and React, including a waterborne disease surveillance system that achieved 87% anomaly-detection precision.
