Johan Karlsson has been working with Xamarin since the days of MonoTouch and Mono for Android, and it all started with writing a game. He is a full-stack developer, currently focusing on mobile applications using Xamarin, but has in the past worked a lot with ASP.NET MVC, Visual Basic.NET (not proud), and C# in general. Also, he's created a whole bunch of databases in SQL Server over the years. Johan works at tretton37 in Sweden and has about 20 years' experience in the trade of assembling ones and zeros.
