02 — About

Engineering systems that
actually scale.

I'm a Senior Software Engineer with 3+ years of experience building backend systems and full-stack applications that perform under pressure. Currently at Geeks2Connect Infotech in Jaipur, where I architect services that handle 10,000+ concurrent users without breaking a sweat.

My toolkit is Python-first — FastAPI is home — but I'm equally at ease in the Node.js ecosystem with NestJS and Express. On the frontend, I build with React and Next.js; on mobile, React Native for both iOS and Android.

I care deeply about clean architecture, measurable performance, and the humans on my team. I've mentored junior developers and led backend squads — because great engineering is as much about people as it is about code.
