Senior React Native Developer – Reconstruct Missing Source Code for Existing Live iOS & Android App

Senior React Native Developer Needed to Reconstruct Missing Frontend Source Code for Existing Live iOS & Android App is an existing mobile application currently published and functioning on iOS and Android. I am looking for a highly experienced React Native mobile developer to reconstruct missing frontend/mobile source code and restore a complete, maintainable development project. This is NOT a new app and NOT a redesign project. The developer must use the existing live application, available project materials, backend/API, assets, documentation, and any existing source-code components to reproduce the current app as accurately as possible. Main Responsibilities Reconstruct the missing React Native frontend/mobile source code. Reproduce the existing live UI, screens, navigation, and functionality. Connect the reconstructed app to the existing backend/API. Restore authentication and existing integrations where applicable. Restore scan/photo/video/AI-related frontend flows that are already part of the live product. Verify iOS and Android functionality. Resolve build/configuration problems. Produce working iOS and Android builds. Ensure the project can be opened, built, modified, and maintained by another React Native developer. Assist with TestFlight/App Store and Google Play testing/build deployment as required. Required Experience Strong experience with: React Native, JavaScript/TypeScript, iOS, Android, REST APIs, authentication, Git/GitHub, Xcode, Android Studio, Apple App Store/TestFlight, and Google Play Console. Experience taking over or reconstructing an existing production application is strongly preferred. Deliverables At completion, I must receive: Complete React Native frontend source code. Complete iOS and Android project/configuration files. All reconstructed screens, components, navigation and assets. Working connection to the existing backend/API. Environment-variable template and configuration instructions — no secrets committed to the repository. Dependency/package files and build instructions. Working iOS build. Working Android build. Source code committed to a GitHub repository controlled by RepairsMe . Technical handover documentation. Confirmation that another independent developer can clone the repository, install dependencies, build the application, and continue development. Important This project will use milestones. Payment for the final milestone will only be approved after the reconstructed source code and builds have been delivered and technically verified. Applicants should explain whether they have previously reconstructed or taken over an existing React Native application and how they would approach this project. Please do not apply if your experience is primarily website development. I need a senior mobile/React Native developer with production iOS and Android experience.
