Jason Awbrey is a Xamarin MVP, frequent speaker, author, and consultant based in Spring, Texas, USA. He has been working with the .NET framework for over 15 years, and with Xamarin since its early beta stages. He is the President of the North Houston .NET Users Group and a co-lead of the Houston Xamarin Meetup.

Jason's company, PostDotNet Consulting (postdotnet.com), is a Xamarin Consulting Partner.

Joe Dan Galyean is the Vice President of Application Development for Cinemark USA. He has been working in the field of software development for 14 years, primarily with .NET technologies.

Paul F. Johnson has many years of experience in cross-platform development. He started his programming career back in the 1980s on 8-bit machines. With a background in chemistry and working experience in education, he developed a large number of applications for students as well as developed code in Fortran for his Master's degree. During this time, he became interested in .NET, especially C# due to its similarities with the other C languages. By chance, a small start-up in the US called Ximian had started to develop an open source implementation of the .NET standard, so being a Linux chap was now no longer a barrier.

Over the years, this interest grew and so did Ximian. Novell bought them out, and after Novell was sold, Xamarin was formed and mobile development was the next stage.

After completing education, Paul worked on the ill-fated WowZapp messenger application followed by a number of other mobile apps on both iOS and Android. All the code for these platforms was in C#, so the idea of cross-platform mobile development was certainly going strong.

In April 2013, Paul began working on a complete rewrite of F-Track Live so that it would run on Android, iPhone, and Windows Mobile. During that time, he was contacted by Xamarin to check whether he was willing to come on board as part of the documentation team.

Paul has written Xamarin Mobile Application Development for iOS, Packt Publishing, and is part way through writing a new book for Packt—again using Xamarin for cross-platform development. He also has a third book in discussion with Packt Publishing for using the Xamarin Mobile platform to create an interactive adventure (including the AI aspects required for it).
