Juliet O
About this gig
HELLO AMAZING BUYERS
Is your Flutter or React Native app crashing, showing errors, or failing to work as expected? I will diagnose and fix mobile app bugs, errors, crashes, and functionality issues to get your application working reliably again.
I can troubleshoot existing applications and resolve issues involving:
- Flutter & React Native bugs
- Android & iOS app errors
- App crashes and runtime issues
- API integration problems
- Firebase & Supabase issues
- Authentication and database errors
- UI/UX and responsive layout bugs
- Build and dependency errors
- Broken features and functionality
- Performance and stability issues
My approach focuses on identifying the root cause rather than applying temporary fixes. I can review your existing code, reproduce the issue, troubleshoot the relevant components, implement the correction, and test the affected functionality.
Whether you're dealing with a single frustrating bug or several related issues, I can help stabilize and improve your mobile application while preserving the existing functionality wherever possible.
Send me the issue you're experiencing, and let's get your app working properly again.

FAQ
What types of mobile app issues can you troubleshoot?
I can troubleshoot crashes, runtime errors, broken functionality, UI issues, API failures, authentication problems, database errors, build failures, dependency conflicts, and performance-related issues in Flutter and React Native applications.
Can you fix an app that crashes during startup or while using a specific feature?
Yes. I can investigate startup crashes, runtime exceptions, and feature-specific failures by tracing the relevant code, dependencies, API calls, and application state to identify and resolve the underlying issue.
Can you troubleshoot Flutter and React Native build or dependency errors?
Yes. I can diagnose common build failures, package conflicts, configuration problems, incompatible dependencies, and platform-specific issues affecting Android or iOS builds.
Can you fix API, Firebase, or database-related problems?
Yes. I can troubleshoot API requests, authentication flows, Firebase/Supabase connectivity, database operations, response handling, and other backend communication issues affecting your application.
Can you fix UI and functionality issues without rebuilding the entire app?
Yes. When the existing architecture is suitable, I work within the current codebase to correct the affected components and preserve working functionality instead of unnecessarily rebuilding the application.
Will you test the fix after resolving the issue?
Yes. After implementing a fix, I test the affected functionality and related flows to verify that the issue has been resolved and that the correction does not introduce obvious regressions.
