I was the sole IT/Systems manager at my last place of employment. I did it all from fix printers, setup email programs, to website administration, database administration. Now I am an Automation Developer using C# and Coypu (wrapper for Selenium). I also do a lot of custom programming in VB6/VB.net/PHP/HTML/Javascrip. Almost all my knowledge is derived from personal experience, trial & error, and from the stackexchange network.
