About Me

I'm a results-oriented Frontend Engineer with 5+ years of experience shipping production-grade web applications. I thrive in agile environments, owning features end-to-end โ€” from API integration to release.

My strengths lie in React, state management, design systems, and continuous delivery. I'm passionate about performance optimization, accessibility, and creating interfaces that feel effortless to use.

Currently at Winwire Technologies in Bengaluru, I lead frontend architecture decisions and help teams ship faster through reusable component patterns.
