I'm a geek.
Mostly, I program C# stuff, everything from XNA, Silverlight, and Windows 8 metro-style applications to ASP.NET, services, and WinForms. I've got a lot of .NET specific stuff under my belt, like WCF, WPF, and the like, but I also do a lot with Databases (all the way down to RDBMS theory), and algorithms.
