Software Developer (Senior) Paddedwall Software
United States United States
I've been paid as a programmer since 1982 with experience in Pascal, and C++ (both self-taught), and began writing Windows programs in 1991 using Visual C++ and MFC. In the 2nd half of 2007, I started writing C# Windows Forms and ASP.Net applications, and have since done WPF, Silverlight, WCF, web services, and Windows services.

My weakest point is that my moments of clarity are too brief to hold a meaningful conversation that requires more than 30 seconds to complete. Thankfully, grunts of agreement are all that is required to conduct most discussions without committing to any particular belief system.

My name is Gus Class, I'm 29 years old, and I have been passionate about computers for my entire life. My first computer was an Apple IIgs and I begged my parents to get a PC (a 386!) around the time I had turned 7 or 8 which they begrudgingly caved in on. I came online for the first time in the early 90s through the Prodigy service which led me to the BBS scene and opened doors for learning the ins and outs of computing. I taught myself how to program in my teens, took vocational classes in high school on network administration through a magnet program, and earned a bachelor's degree in Computing and Software Systems through the University of Washington in 2003. In an effort to round out my education, I earned an MBA in 2008 while working full time at Microsoft.

I am currently a Content Project Manager at Microsoft where I have worked for the past 5 years. My work there has included writing sample code, creating compelling documentation to help developers adopt Windows features, managing sites, connecting with the developer audience through social media, mentoring and growing new hires and peers, developing tools to enhance productivity, and attending conferences as a Microsoft representative.

I enjoy a plethora of hobbies including rock climbing, DJing, electronic music production, recreational programming, creating web sites, playing and creating video games, and hanging out with social media mavens.
