Mobile App QA Tester for iOS

I need an experienced QA tester with UI/UX review experience to test GetJabb, an on-demand service marketplace app, across iOS TestFlight, Android, and web. GetJabb allows requesters to post tasks and workers to apply for local service jobs. The tester should check the full requester and worker experience, including login, signup, onboarding, task posting, worker application, requester selecting a worker, location/address search, profile flow, payment flow readiness, error messages, loading states, empty states, navigation, UI clarity, trust, and overall usability. The tester must test on real devices where possible and provide a detailed bug/UX report with screenshots or screen recordings, severity level, device/OS/browser used, steps to reproduce, expected result, actual result, and clear recommendations for improvement.
