I need an experienced mobile developer to hunt down and eliminate a series of recurring bugs in my live Android and iOS app. The issues range from intermittent crashes to unpredictable behaviour that only surfaces after the app has been running for a while. What I need from you is a thorough code-level audit, clear replication steps, and robust fixes that can be verified through TestFlight and a closed Android testing track. You will receive full access to the source repository, current build pipelines, crash logs (Firebase Crashlytics and Apple’s diagnostics), and a small set of test accounts. Once the root causes are identified, please patch the code, document every change, and prepare new production-ready builds. A concise changelog outlining the fixes and any refactoring is essential. Deliverables: • Clean, stable Android (.aab) and iOS (.ipa) builds ready for store submission • Step-by-step summary of the debugging process and resolutions • Brief post-fix report confirming that all crashes are resolved and no new ones introduced If you are comfortable working across Swift/Kotlin or a shared framework such as React Native or Flutter, can set up local debugging quickly, and have a solid track record of publishing polished releases, I’d love to collaborate. Include an estimated timeline and a couple of examples of similar troubleshooting jobs you’ve successfully completed.
