I will fix react native app bugs crashes and performance issues


About this gig
Are you facing crashes, build errors, API issues, UI bugs, or slow performance in your React Native application?
I will professionally diagnose and fix bugs in your React Native CLI or Expo app for Android and iOS. My goal is to provide a stable, smooth, and maintainable solution without unnecessary changes to your existing codebase.
I can help with:
App crashes and runtime errors
Android and iOS build issues
API integration and authentication problems
Firebase configuration and notification issues
UI, layout, navigation, and responsiveness bugs
Redux, state management, and data handling issues
Slow loading, lag, unnecessary re-renders, and performance problems
Package, Gradle, CocoaPods, and dependency errors
You will receive clean code, proper testing, clear communication, and a summary of the changes made.
Please contact me before placing an order so I can review the issue, confirm the scope, and recommend the correct package. New features, full app redesigns, backend development, and store publishing are not included unless agreed separately.

FAQ
Do you work with both React Native CLI and Expo?
Yes, I can troubleshoot and fix issues in both React Native CLI and Expo applications. Please share your project setup and React Native or Expo version before ordering.
Can you fix both Android and iOS issues?
Yes. I can fix Android, iOS, or cross-platform issues. Please mention the affected platform and package the project accordingly.
Should I contact you before placing an order?
Yes. Please contact me first with the error details, screenshots, logs, and source-code information. I will review the issue and recommend the correct package.
What information do you need to investigate the bug?
I need the source code, clear reproduction steps, screenshots or screen recordings, error logs, device details, operating-system version, and the expected application behavior.
Can you fix Android build and Gradle errors?
Yes. I can troubleshoot Gradle configuration, dependency conflicts, SDK compatibility, signing configuration, native-module, and release-build issues.
Can you fix iOS and CocoaPods issues?
Yes. I can troubleshoot CocoaPods, Xcode build errors, deployment-target issues, native dependencies, permissions, and iOS configuration problems.
Do you fix API, login, and Firebase issues?
Yes. I can fix API integration, authentication, token handling, Firebase configuration, push notifications, and data-loading issues. Backend changes are priced separately.
Is a new feature included in the packages?
No. These packages cover existing bugs and performance issues. New features, screen development, backend changes, or major redesigns require a separate custom offer.
Will you publish the application to the stores?
Store publishing is not included by default. Google Play Store or Apple App Store deployment can be added through a custom offer after reviewing the project.
Do you guarantee that every issue can be fixed?
Most development issues can be resolved, but the solution depends on source-code quality, third-party services, available credentials, deprecated libraries, and backend access. I will review the issue before confirming the order.
