WHO AM I_

I'm a Full-Stack Developer based in Patna, Bihar, with 3 years of experience shipping production-grade software. I specialize in building high-performance, real-time applications with clean architecture.

My professional journey spans a real-time sports trading system at Avarna Technology LLP - handling live WebSocket streams, order management, and complex trading UIs - to building a complete multi-tenant ecommerce platform from the ground up.

Currently pursuing my MCA in AI/ML at Chandigarh University while continuing to build and ship at scale.
