Building a cross-platform mobile app that runs seamlessly on both iOS and Android. The stack is React Native, and I will hand over wireframes, brand assets, and the REST/GraphQL endpoints you’ll be calling. Your task is to translate those designs into a clean, maintainable codebase and guide the project all the way to App Store and Play Store submission. Core scope • Secure user authentication (email and social log-in, plus password reset) • Push notifications wired through Firebase/APNs, with in-app handling for deep-links and badge counts • In-app purchases that cover both consumables and subscriptions while satisfying Apple/Google review guidelines Acceptance criteria 1. A single codebase that compiles without errors for iOS (Xcode) and Android (Gradle). 2. Successful sign-up, sign-in, and token refresh flows against our backend. 3. Push notifications delivered in foreground and background, with user-tappable actions routed correctly. 4. Purchase flow completes, receipts are validated server-side, and test purchases appear in sandbox/alpha tracks. 5. Store-ready builds plus a short README explaining environment vars, build commands, and release steps. I prefer TypeScript, React Navigation, and either Context API or Redux for state, but I’m flexible if you present a solid alternative. Regular Git commits, a brief weekly video demo, and responsive communication are expected so we can iterate quickly. Send a short note describing similar React Native apps you’ve shipped and any experience you have with in-app purchases or push services. Let’s get this into users’ hands soon.
