I’ve been at Microsoft since the late nineties (started as an intern in ’98) and have worked on Visual J++ 6, Visual Studio 2002, 2003, 2005, 2008, and 2010. More specifically, I worked on the C# Compiler from 1.0 through the early stages of 3.0, a couple years on the Developer Division’s deployment technology team, another couple of years on the Cloud Tools team which was responsible for the Windows Azure Tools (through v1.2), and am presently a development manager on the JavaScript team.
You can find my blog on MSDN here though it’s by no means regularly updated anymore.
