About
Nice to meet you — web & mobile developer in Mumbai
I'm a web & mobile application developer with nine years of experience building products for startups and remote teams.
I care about software that's fast, accessible, and genuinely good to use. Lately I've been putting more time into open source and helping the community grow. Whether it's a web app, a cross-platform mobile app, or a desktop tool, I like owning a problem end-to-end — from the data model to the last pixel.
Fast, accessible React.js & Next.js apps.
React Native + Expo — iOS & Android from one codebase.
UI/UX in Figma — wireframe to shipped interface.
Electron apps for macOS, Windows & Linux.
Stack
One system, many surfaces — React, React Native & Node.js
The tools I reach for, and how they connect — React on top, Node and a small graph of data tools underneath.
Architecture
How I usually wire an app — a React / Next.js front end talking to the server through GraphQL and API routes, then Hasura Cloud serving instant GraphQL over Postgres, with Firebase and Auth.js handling data and auth.
Core
Ecosystem
Open source
Building in the open — React Native open source
All repos on GitHub →I like giving back to the tools I use every day. A few projects and contributions I'm proud of:
Routing and navigation for React Native and web apps.
Easy to customise, easy to use UI elements for React Native.
A wrapper around React Native Reanimated that makes the animation system easier to use.
Material Design components for React Native (Android & iOS).
A lightweight game engine for React Native.
Calculate a resistor's value from its colour bands, without the effort.
