We are currently building the desktop/laptop version of our OpenVPN application, but we are seeking to outsource the development of our mobile version. We utilize C# for everything that we do and would like this mobile app to be built using Xamarin tools for Android, iOS, and Windows Phone. As much of the codebase as possible should be shared across all mobile platforms with the GUI differing as necessary, of course. Target functionality is non-root OpenVPN. PPTP and L2TP are optional but desirable. The application should be very competitive when compared with the mobile apps for the leading VPN service providers. Our top priority is easy-of-use for novice users, while also offering more advanced options for power users. There is more to share, but this is a general overview. This will start as a one-time project, but if the work is satisfactory it could turn into an on-going project as updates/changes are needed.

I need an experienced Phonegap developer to fix bugs in a Phonegap live radio streaming app on iOs. The app works ok in Android 4.4/5, but in iOs it freezes until I switch on/off network access.

I am using Phonegap Build and code is stored in private repository in Github.
