I'm a software developer and a book author, mainly working on low level software developments, quite adept to Windows and Linux driver development. I've been using C as my programming language for about 6 years. My driver development experiences are still limited to Windows 2000/XP and Linux kernel 2.4. Well, I'm back trying to catch-up with the rest of the industry in those subjects. Over the years, I've been working on BIOS reverse engineering as well.
