We already have a very simple Android app written in Mono for Android (C#). We need someone to port this simple app to Windows Phone. All you need to do is to port the UI code. We have 7 simple UIs written in Mono (C#), so you need to recreate those UI in WPF. I expect this porting to be done in 1 week.
You need to have good experience in Windows Phone and WPF development.
