About Me

Backend engineer at Trames, working mainly with TypeScript, Node.js, PostgreSQL and AWS.

Outside work, I build Orbica — an open space encyclopedia covering rockets, satellites and launches since 1957, with live 3D orbital tracking.

Previously built and shipped backend systems serving ~200K users at Thaagam Foundation using Django, PostgreSQL, Redis and the WhatsApp Business API.

Currently finishing an MCA alongside full-time engineering work.
