I'm Zohaib Naseer, a senior full-stack and mobile application developer using Agentic AI, React Native, React.js, Next.js, TypeScript, Node.js, NestJS, Android with Kotlin, iOS with Swift, and the web platform. I help startups and product teams ship React Native app development, mobile performance optimization, and native Android/iOS integrations that hold up in production.
I also build open-source packages on GitHub and write code for products that need to scale across mobile and web.
I'm based in Lahore, Pakistan, and I work remotely for global teams.
I have built and supported 30+ mobile and web projects across fintech, marketplaces, healthcare, food delivery, social platforms, and offline-first applications.
I'm the author of react-native-bg-geolocation (v0.2.3), a production-ready package for background location tracking, geofencing, and Android headless tasks.
