My production React Native app has started throwing functionality errors on both iOS and Android. Features that previously worked—navigation flows, API calls, and a couple of in-app actions—are now either unresponsive or crashing unexpectedly. I need someone who can step in quickly, reproduce the issues on each platform, trace the root cause, and patch the code without introducing regressions. Scope of work • Audit the current codebase (React Native, TypeScript, Redux) and reproduce the functionality issues on a recent iOS device/simulator as well as an Android device/emulator. • Identify any library version conflicts, deprecated APIs, or platform-specific edge cases causing the breakage. • Implement clean, test-covered fixes and supply updated builds: an .apk/.aab for Android and an .ipa via TestFlight for iOS. • Provide a concise changelog and highlight any refactors that may affect future releases. Acceptance criteria 1. All previously broken user flows operate without error on iOS 16+ and Android 11+. 2. No new warnings appear in Xcode or Android Studio build logs. 3. Unit and basic UI tests pass (I’m using Jest and React Native Testing Library). 4. Delivery includes a pull request or patch file plus instructions for reproducing the fix. If you are comfortable diving into a live React Native codebase and turning around reliable fixes fast, let’s get started right away.

Since navigation, API calls and in-app actions that were already working are now failing on both iOS and Android, I’d first look for what changed underneath them rather than treating each error as a separate bug. In a React Native app, a dependency/native API change can show up as several unrelated-looking failures. I’d reproduce the first failing flow, trace it through Redux/API/navigation, then compare the recent package and platform changes to find the actual break point. Once that’s fixed, I’d rerun the affected flows on both platforms and use your existing Jest/RNTL tests to make sure the fix doesn’t create another regression. Then I’d prepare the Android build and TestFlight build and keep the PR/changelog limited to what actually changed. Did the problems start after a recent React Native/package update, or did they appear without any dependency/code changes? If you share the repo and one reproducible failing flow, I can start from there.

Hi, I can step into your existing React Native app and trace why previously working flows are now crashing or becoming unresponsive, rather than masking the symptoms with quick patches. I’ll: • Reproduce the issues on both iOS and Android • Trace navigation, API and Redux-related failures • Check library conflicts, deprecated APIs and platform differences • Apply clean fixes with Jest/RNTL coverage • Verify release builds and provide the patch/PR + changelog I have hands-on experience with React Native, Android/iOS, APIs and production mobile apps. Send me the repo and the first reproducible issue, and I’ll start with the root-cause diagnosis

Hi, seeing a React Native app break on both iOS and Android at once usually means a recent dependency update or a subtle type mismatch in the Redux store rather than a complete rewrite. I would start by isolating the specific navigation and API calls that are failing to pinpoint the exact line of code causing the crash. I've debugged similar issues where a single deprecated API call in the Redux middleware would freeze the entire app, so I know how to trace that down quickly. A common mistake developers make is patching the symptom without checking the underlying data flow, which often leads to the same error popping up again in a different screen. I will run the unit tests to verify the logic and then build the APK and IPA files to ensure the fix works on real devices. I am ready to start immediately and can have the updated builds in your hands as soon as the root cause is confirmed.
