Network Engineer by profession. But I tackle pretty much anything, I troubleshoot and solve problems for a living. A days work can range from fixing pumps at a petrol station, to updating a PEP/terrorist list because of changes in the situation in the Ukraine, to soldering a capacitor on a motherboard, to upgrading a GPS system on an aeroplane, to building a server and domain, or monitoring a WAN by remote, or cabling a building, or translating a manual, or a bunch of other stuff. Teaching myself how to program mostly so I can make little programs in my own language for my kids.
I have a varied work history, I left school very young, and went to University as an adult. So my work history is about half blue collar and the latter half white collar. I'm mostly self-educated but I have broad interests.
