About

I'm a React Native and Expo developer who cares about clean code and smooth user experiences. I've built and shipped apps to the App Store and Google Play, from a job portal to an e-commerce marketplace to a real estate rental app.

I work with Redux Toolkit and RTK Query for predictable state, integrate complex APIs, and handle the full release process, including App Store Connect and Play Console requirements.
