Building the full stack
from screen to server.
I design and ship production mobile products end to end — React Native interfaces, native Kotlin bridges, and the Node.js backends that power them.
Same engineer, four layers deep
I'm Ujjwal, a full-stack mobile engineer who's comfortable moving from a scroll animation in React Native down to the Kotlin service keeping it alive in the background, down again to the Express route that feeds it data.
Most of my recent work lives inside a connected product ecosystem — a hiring platform and an HR/attendance system that share infrastructure, users, and a lot of hard-won lessons about what breaks in production.
I care about shipping things that actually work on a real device: correct background services, resilient network states, builds that pass Play Store review the first time, and UI that doesn't feel like a demo.
