I'm Zohaib Naseer, a full-stack mobile application developer using Agentic AI, React Native, React JS, Next JS, TypeScript, Node, Native Android, Native iOS, 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.
For teams that need one senior engineer to move fast, I focus on shipping mobile products that are stable, measurable, and easy to grow.
Build and ship cross-platform products with React Native, Expo, TypeScript, native integrations, and a production-ready release process.
Improve startup time, rendering, lists, image handling, animations, memory usage, and app stability on Android and iOS.
Connect mobile apps to Next.js, React, Node.js, databases, real-time services, analytics, and cloud infrastructure.
These are the React Native notes and service topics I share with teams when they ask about performance, architecture, Expo, testing, releases, security, or hiring help.
