What I'm looking for

I’m looking for a role where I can own end-to-end delivery with strong React frontend focus and production-ready APIs, and build AI-powered features (LLM streaming, safe error handling, rate limiting) in a collaborative, international team.

I’m a Full-Stack Software Engineer with 8+ years of experience building production web applications for enterprise clients and government institutions, with a strong emphasis on frontend delivery in React, TypeScript, and modern CSS. I balance that with hands-on backend capability in API design and database management, so I can translate complex business requirements into working software end-to-end.

Recently, I’ve been building AI-powered features with LLM API integration—shipping streaming responses, inline text transformation, and production-grade error handling including rate limiting, audit logging, and auto-retry on transient errors. I thrive working with international, cross-functional teams (including remote collaboration) to align on goals, gather and refine technical specifications, and deliver reliable systems with clear documentation and maintainable workflows.
