Rock Solid Me
Back in the old days of C++ I took a Design Patterns course offered by the Sela Group. The lecturer was both a highly knowledgeable professional and a very skilled presenter, a combination that I learned to appreciate as I gained more experience in the software industry.
Later on, when it was time to transition to .NET (actually, the time had come a little earlier), I had the enormous privilege to learn from the then-CTO of Sela, who infected me (as well as other students) with his great excitement over the platform and the tools (I believe Visual Studio 2005 just came out of beta). Needless to say, the course was a huge success (despite the all-too-well known budget constraints, which stripped it of almost all labs, as usual).
As of today, the Sela Group employs a host of world-class experts in virtually all areas of the .NET technology ecosystem -- internals, WPF, WF7, EF, TFS and mad skillz -- to name just the few I had personally heard or worked with.
I am overwhelmed to have joined the elite club that the Sela Group is.
