I need a fast-moving React Native developer to jump into my existing iOS and Android codebase and resolve three blocking issues before tomorrow: • UI scaling must look correct on both an iPhone 14 and a Samsung Galaxy S23. • All buttons need to be fully responsive and properly aligned across every affected screen. • The user profile page crash has to be eliminated and the app must run without unexpected terminations. You’ll work directly in my private GitHub repo, pushing incremental commits so I can verify progress on TestFlight and an internal Android build. The final commit should leave the app stable, visually consistent on the target devices, and free of the profile-page crash. Please be comfortable with React Native debugging tools, simulators, and on-device testing for multiple screen sizes. A single-day turnaround is critical, so only take this on if you can begin immediately and deliver the fixes within 24 hours.
