Your mobile app deserves to actually ship and stay live, not get stuck in a perpetual beta or rebuilt from scratch a year after launch. I'm Asjad Raja, a Senior React Native Developer with 5+ years of experience building cross-platform mobile apps for iOS and Android. I work in both the React Native CLI and Expo workflows, so the toolchain gets picked based on your project's actual constraints native module needs, OTA update requirements, team size instead of a default. What that looks like in practice: native device integration through Expo-Camera and device APIs, location-based features built on Google Maps with custom markers and live data overlays, push and scheduled local notifications, offline-friendly state with AsyncStorage and Context API, and Firebase-backed auth, real-time data, and cloud storage when a lightweight backend is the right call. I've taken apps through the full lifecycle architecture, build, OTA updates, and App Store / Play Store submission including a location-based EV charging app that's live and publicly downloadable on both stores today. That's the level of finish I aim for: not a working build, a shipped product. Because I also work as a full-stack engineer (Next.js, Node.js, Express, MongoDB, PostgreSQL), if your mobile app needs a custom backend, an admin dashboard, or a web companion app, I can build that piece too without bringing in a second contractor and re-explaining your product from scratch. Where I've shipped real apps: health and nutrition tracking, family and productivity tools, location-based services, gamified consumer apps, and AI-assisted recommendation features layered into mobile UX. Clients across the US, EU, and AU keep coming back for strong async communication across time zones, early flags on platform-specific risks App Store review gotchas, native module conflicts before they become a fire drill, clean documentation, and a long-term partnership mindset, not a one-off task executor. If you've got a mobile app that needs to go from idea to App Store, or an existing app that needs rebuilding the right way, send me a quick overview and I'll map out the architecture, the Expo-vs-bare-RN call, and a realistic timeline. No fluff, no overselling.
