Anuja K.
Mobile App Developer | Flutter, React Native | iOS & Android Apps
I'm a mobile app developer. I build, fix and launch iOS and Android apps in Flutter and React Native, from booking and ecommerce apps to learning apps, and I handle the backend and App Store release too. Top Rated Plus with $100K+ earned on Upwork. The quickest way to judge my work is to open the apps. These are live in the stores today: - Hire N Ride: a bike and car rental marketplace app. I rebuilt the customer app in Flutter in 2026 (previously React Native), and there's a separate host app for vehicle owners. Search, booking, payments, KYC and push notifications. - The India Decor: a home decor shopping app with catalogue, cart, checkout, order tracking and push notifications. - Explicit Cars: a car listing app for a client, which I build and publish on both stores. - The Mark Academy: a corporate learning app for a US client with video lessons and spaced-repetition quizzes. I ship its iOS and Android releases. What I usually get hired for: - New iOS and Android apps from idea to App Store and Google Play, including developer accounts set up in your name - Cross-platform and hybrid apps in Flutter, React Native, Expo and Ionic - Taking over an app someone else built: reading the code, fixing bugs and getting releases moving again - Upgrades that keep apps in the stores: SDK and API-level updates, Ionic/Capacitor and React Native version upgrades, review rejections - In-app purchases, subscriptions, Stripe payments and push notifications - Backend work behind the app: Node.js APIs, Firebase (auth, Firestore, push, functions), PostgreSQL, MongoDB - App Store optimization and pre-launch audits: a written list of what blocks release and what can wait How I work: I agree a written scope with you first, you get test builds on TestFlight and Play internal testing as I go, the code sits in a repo you own from week one, and I write a README so another developer could pick it up. I'll also tell you when not to rebuild. Most apps that come to me don't need a new framework, they need the existing one cleaned up and shipped. Send me your idea or your repo and I'll reply with what I'd do first.
