I need a seasoned mobile developer who can deliver a complete, production-ready e-commerce app that runs smoothly on both iOS and Android. From setting up the first project file through to publishing in the App Store and Google Play, you’ll handle every technical step. Core scope • Build native-quality apps for both platforms (I’m open to React Native, Flutter, Swift/Kotlin—whatever you’re fastest and most confident with). • Implement secure user registration and login, including password reset. • Integrate a reliable payment gateway so customers can check out without friction. I’ll supply the product data and back-end endpoints; you wire everything together, polish the UX, and guide me through test builds and final submission. Clean, well-commented code, a brief hand-off document, and successful store approvals are the final acceptance criteria.
