I build backend systems that run in production. My work focuses on Django-based REST APIs, real-time WebSocket services, and PostgreSQL-backed architectures. Most of what I've built has been for actual clients — not just portfolio pieces.
Currently completing a B.Tech in Computer Science (Data Science) at University of Mumbai (2026).

I started freelancing in 2021 while studying. Most of my projects were for clients who needed working systems, not demos — which meant dealing with real constraints: deployment on actual servers, handling real user traffic, and maintaining code other people depend on. That experience has shaped how I approach backend work.
