About

I'm a Frontend Developer based in Noida, India, building production web and mobile products. Currently at Appeneure, shipping React Native apps to the App Store and Play Store.

I build mobile apps, and lately the infrastructure underneath them — BLE hardware integration, in-app subscriptions and real-time data sync. I like shipping end to end and finding out what actually breaks on a real device.

My focus is frontend architecture, performance, and seamless user experience. I work primarily with React, Next.js, React Native, and TypeScript — turning complex problems into clean, intuitive interfaces.

I graduated from Dr. A.P.J. Abdul Kalam Technical University with a B.Tech in Computer Science.
