Xamarin Android Push-to-Talk Walkie-Talkie App

I'm looking for a skilled developer to create a Xamarin Android WebRTC application for me. This app will function as a push-to-talk walkie-talkie, focusing on audio transmission.

Key Features:
- The primary function of the app will be to allow users to communicate in a push-to-talk manner, similar to a traditional walkie-talkie
- High-quality audio transmission is essential
- The app should be developed specifically for Android platforms

Ideal skills for this project include:
- Extensive experience with Xamarin
- Proficiency in Android app development
- Deep understanding of WebRTC and SFU (Selective Forwarding Unit) solutions
- Strong skills in implementing real-time audio transmission

Please note, the goal is to create a seamless, reliable, and user-friendly push-to-talk application.
