Project description:
"My React Native chat app (iOS and Android) relies on a Node.js backend and WebRTC for voice calls.

Right now the call experience is unstable and I need an experienced engineer who can jump in, trace the problems end-to-end, and deliver a solid fix within three days.

The current pain points are clear:

• Call status often desynchronises between caller and callee
• One-sided or completely silent audio streams appear at random
• Switching between earpiece and loud-speaker is unreliable
• Ringtones keep playing after a call connects or ends
• Behaviour degrades noticeably on weak networks or when the same user is logged in on multiple devices
• The project also throws miscellaneous build/runtime errors that must be cleaned up while you are inside the codebase

What you will actually deliver:

1. Stable, two-way voice calls across both platforms with correct status updates, audio routing, and ringtone handling
2. Clean builds with no console or compile-time errors
3. Repeatable test results on at least one recent iPhone and one flagship Android device (I will run additional regression tests)
4. Assistance pushing the patched code to production and verifying it in TestFlight / Play Store internal tracks

I will give you full access to the React Native repo, the Node.js signalling server, and our WebRTC configuration. Please outline relevant projects where you have solved similar real-time communication issues; that experience is the only thing I need to see up front.

If everything goes smoothly there is a backlog of new features waiting, so this quick rescue mission can turn into long-term collaboration." (client-provided description)
