About

I build systems that don't break under pressure.

I'm a backend engineer based in Bengaluru with 2+ years of production experience at Paytm, where I design the gamification engine behind Spin the Wheel, Scratch Card & Lucky Draw for millions of users.

My multithreaded scheduler pushed scalability up 40% and cut latency 60%. I've shipped redemption systems handling 1M+ transactions a day at 99.9% data integrity — and I love the hard parts: concurrency, distributed systems, and shaving milliseconds off every API.
