React Native (Expo) Developer Needed to Fix Frontend Bugs in Existing Mobile App

I am looking for an experienced React Native developer with strong Expo experience to help fix several frontend issues in an existing mobile application. The app is already developed and functional, but there are a number of UI/UX and frontend-related bugs that need to be identified and resolved. We are looking for someone who can quickly understand an existing codebase, troubleshoot issues efficiently, and deliver high-quality fixes. After fixing this app, I need to publish this app to the app store and google store.
