Using the .net for unix Mono project and the Xamarin.com IDE, I am currently developing a mobile application that deals with the analysis of geotagged photos and that will be released in early 2015. In this project i was able to reuse almost 60% of the shared code base with only the presentation layer differing. Technologies used: Xamarin IDE, .NET, IOS SDK, Android SDK (API Level 18+), SQLLite.
