Our mobile app was working until we upgraded tools. Now the iOS build fails in Xcode 16 with pod and signing errors, and testers on Android 15 report a crash on launch. I can send the logs and repo access. I need the build fixed on both platforms, dependencies updated sensibly, and a signed build uploaded to TestFlight and Play internal testing.

We cannot ship a bug fix that users have been waiting for.

Key Deliverables:

• Codebase Review & Initial Implementation: Reviewing existing code, setting up development environment, and beginning core work.

• Feature Implementation & Testing: Completing primary deliverables with automated and manual testing.

• QA Verification & Production Deployment: Final cross-browser/device testing, staging verification, and production handoff.

Requirements:

• Demonstrated experience with React Native, Flutter, Xcode, Android Studio, Mobile Debugging

• Quick turnaround needed — must be available to start within 24 hours.

• Must test on both mobile and desktop before requesting milestone release.

• Don't change the existing database schema without discussing first.
