Geoffrey has been actively involved in the Xamarin community and leading projects using this breakout technology since 2012. He is one of the maintainers of the popular ReactiveUI functional reactive programming MVVM framework.

As part of constant and never ending learning, Geoff is actively engaged in contributing to the Xamarin and Microsoft .NET open-source community.
