Tester Android & IOS (React Native) -- 3

I am looking for a skilled tester experienced in Android and IOS with React Native. The project is for a long-term basis and will require more than 20 hours of testing. I do not have a specific app or feature in mind that needs testing, so I need guidance on what to test. The ideal candidate should have experience in testing mobile applications, be detail-oriented, and have excellent communication skills.
