Hi,
I am interested to work on this. I have worked on WebRTC projects but those were for Android app. In short you need to setup a STUN server for your webrtc peer. This is typical NAT problem, in which webrtc peers unable to find actual public address of next peer which are behind the firewall.
I am ex-Microsoft employee and have 8+years experience in software development and customization usingwide range of Microsoft technologies (C#, ASP.NET, MVC,WPF, Window form, Sql Databases, Azure, Sync framework etc.), Mobile technologies - Android, Xamarin and server side language node.js and Golang. Since i have previous experience in such applications, so I think it will help in this project, if selected.
Let me know, If you find me suitable for this project and share complete details. If you want more details, we can discuss over chat/ skype.
Regards,
Shashi Bhushan
