Different levels of expertise with MSSQL (T-SQL), .NET (C#, VB.Net), Web Services, XCode+iOS, Android, Xamarin, VMWare, Active Directory, 3CX and other technologies.
I particularly like the WebServices/mobile world. The current generation of cloud hosted and connected applications is very interesting to me, and I am shifting my work towards that area.
I have also done some hobby level (Arduino) robotics/electronics and 3d printing.
