Been working in IT for a while.
Started on helpdesks, moved onto PC support, later did server stuff, dial up networks, ISDN, LANs, WANs, switches, routers, you name it. If it's something to do with IT support, chances are I've done it.
Never coded anything until I started doing Amiga asm coding from scratch in 2007 though. I suppose that's why I'm not as powerful as a lot of the pro coders out there - strictly just an amateur enjoying himself.
