About Me

Building things that scale

I'm a backend engineer who loves turning complex problems into elegant solutions. Currently at Razorpay, building the infrastructure that powers payments for millions of businesses across India.

Before Razorpay, I honed my craft at Rakuten leading backend teams, and at Brillio optimizing enterprise applications. I even co-founded Newsio, an AI-powered news app that hit 750+ downloads and maintained a 4.8-star rating. Not bad for a side project! 🚀

When I'm not writing Go or wrestling with Kubernetes, you'll find me solving algorithm puzzles (250+ and counting on LeetCode), or practicing one of the 6 languages I speak - English, Hindi, Telugu, Kannada, Tamil, and German.

Quick hits:

  • 🎯 Built observability systems that reduced MTTD by 40%
  • ⚡ Improved app performance by 20% at Brillio
  • 🌍 Polyglot - 6 languages and counting
  • 🎮 Led teams from 3 to 7 engineers
