React Native / Expo Developer Needed for Small Existing App Fix

**React Native / Expo Developer Needed for App Testing, Bug Fixes & AI-Assisted Improvements** I have an existing mobile app built with **React Native / Expo**. The app is already working and has both iOS and Android builds. We are moving to version 4 now. I need a careful React Native / Expo developer to help on an ongoing basis with: * Bug fixes for version 4 release and future releases * Small feature improvements * Release-version testing on real iOS and Android devices * Troubleshooting before public release * Reviewing and assisting with AI-generated code from tools such as Cursor, Manus, Claude Code, Codex, or similar This is **not a rebuild**. I do not want the app architecture rewritten. I need someone careful, practical, and comfortable working on an existing codebase. **Must-have coding experience:** * React Native / Expo * TypeScript or JavaScript * Existing mobile app maintenance * GitHub branches and pull requests * Testing on real iOS and Android devices * Clear written English communication * Careful review of code before delivery * Comfortable using AI coding tools while personally checking the work The first task will be small and paid as a trial. If communication and work quality are good, there may be ongoing work. Please include: 1. Your React Native / Expo experience 2. Whether you can test on real iPhone and Android devices 3. Whether you are comfortable with GitHub pull requests 4. Which AI coding tools you use, if any 5. Your availability this week 6. Your hourly rate or estimate for a small first task
