I need a production-ready e-commerce application built in React Native, targeting iOS first. The objective is to give customers a flawless shopping journey—from browsing products to completing a secure payment—so the build can go straight to TestFlight and then the App Store. Once the iOS version is stable we can reuse the same codebase for Android, but the immediate milestone is a polished iOS release. Key deliverables • A clean, well-structured React Native (TypeScript) codebase stored in Git • End-to-end product catalogue, search, cart, and checkout flow with a payment gateway fully integrated • Seamless connection to existing REST/GraphQL endpoints, complete with error handling and offline caching • Thorough unit and integration tests plus an automated build pipeline that produces TestFlight artifacts • App Store-compliant performance, accessibility, and privacy practices, documented for future maintenance Acceptance criteria • The app installs and runs on physical iOS devices running iOS 15+ • All critical user flows—browse, add to cart, pay—complete without crashes or UI glitches • Automated test suite covers critical logic at >80 % and passes in CI • Code review shows adherence to industry best practices and clean architecture principles Share links to any React Native e-commerce or payment-heavy apps you have published, and briefly outline your release strategy and preferred testing stack.
