01 — About
Code that
feels as
good as it works.
I'm a frontend engineer with over a decade of building UIs that users actually enjoy. From pixel-perfect CSS to architecture decisions that scale — I've been the person making sure the interface doesn't let the product down.
Currently at Cognizant as a Senior Associate in Hyderabad, I'm helping the banking sector modernise — using GitHub Copilot to analyse legacy C++ systems and drive React-based feature releases. Engineering meets detective work.
But I'm not just a builder. I think deeply about why things are built the way they are. My next chapter is in UX Consulting, Design Product Management, or UX Architecture — bridging the gap between engineering reality and design vision.

Good work deserves
a cold one.
I run on curiosity, caffeine, and the occasional cold beer. If my work, photography, or stories added something to your day — you know what to do.
