Bit of a jack of all trades really in programming terms. Spent a bit of time with embedded C, emdedded Linux, RTOS, PHP/MySQL, Win32/MFC, and can just about order a meal in a handful of other languages. I must be fairly proficient in native C/C++ by now, but couldn't really call myself an expert in any one area - Win GUI stuff in particular, which is the bane of my life at the moment, and for which I find StackOverflow an extremely useful resource.
