01>About

Engineer who ships.

I build systems that work in real time, under real constraints, for real users.

Fullstack developer (Next.js · Go · WebSockets) with production experience building real-time collaborative systems and full-featured web applications. Won Smart India Hackathon 2025 at the national level, delivered a complete full-stack platform under competition conditions. Seeking a web/backend internship where I can contribute to product-focused engineering teams.

I work across the entire stack — from designing interactive frontends with React and Next.js to building high-performance backends in Go and Python. I'm particularly drawn to real-time systems, collaborative tools, and AI-powered applications.
