Between the MSDN forums and some e-mails that I've received, I am seeing a common theme among some of the questions; they deal with undocumented features of Windows phones...

I attended Southern Polytechnic State University and earned a Bachelors of Science in Computer Science and later returned to earn a Masters of Science in Software Engineering.
 
For the past few years I've been providing solutions to clients using Microsoft technologies for web and Windows applications.
 
While most of my CodeProject.com articles are centered around Windows Phone it is only one of the areas in which I work and one of my interests. I also have interest in mobile development on Android and iPhone. Professionally I work with several Microsoft technologies including SQL Server technologies, Silverlight/WPF, ASP.Net and others. My recreational development interest are centered around Artificial Inteligence especially in the area of machine vision.
