About

Systems that hold up
under load.

I work across the whole stack, and lately on RAG-based AI systems: typed React and Next.js interfaces on one end, authorization pipelines, caching and rate limiting, message queues and WebSocket state on the other. Owning both ends means the contract between them is something I design rather than inherit.

Alongside that I compete regularly - 500+ problems on LeetCode, Specialist on Codeforces - and spent a year as president of my college coding club, mentoring students in DSA and software engineering.
