I will fix and optimize your react native expo mobile app
About this Gig
I'm a Full Stack Developer with 5+ years of experience, specializing in React Native and Expo. I help fix, modify, and optimize existing mobile apps for Android and iOS.
If your app has bugs, crashes, build errors, slow performance, or needs new features, I can inspect the existing codebase and implement a reliable solution.
What I Can Help With
- Bug & Crash Fixes JavaScript/TypeScript errors, red/white screens, crashes, navigation issues, API errors, and UI bugs.
- Performance Optimization Slow loading, laggy screens, unnecessary re-renders, memory issues, and inefficient code.
- Feature Additions New screens, REST APIs, authentication, push notifications, analytics, in-app purchases, and Expo modules.
- Expo & React Native Updates Expo SDK upgrades, dependency conflicts, build errors, and compatibility issues.
- UI & Code Improvements Responsive UI fixes, component improvements, and code cleanup.
I focus on finding the actual cause of the problem, not just applying temporary fixes. You will receive the updated source code and a clear explanation of the changes.
