Software engineer specialising in full-stack, backend and AI/ML systems — I design, build and ship products end-to-end.

01 · About

Software engineer building full-stack, backend & AI systems.

Software engineer with hands-on experience across full-stack development, backend engineering and applied AI/ML. I enjoy shipping products end-to-end using Python, TypeScript, React, FastAPI, Node and modern ML tooling — turning ideas into deployed systems that serve real users.

Recent work spans building enterprise document-intelligence platforms at TCS, an offline RAG system for DRDO researchers, and shipping personal products like Nova, GraphMind AI and ChessMeet India.
