I’m a computer nerd.
When I was a kid, I had one of these:
I learned to code on it and wrote clones of Tron Light Cycles, Centepede, and Spy Hunter (among others).
When I went to college I studied Mechanical Engineering because it seemed like a good idea at the time. I even got a masters degree in Industrial Engineering (and Engineering Management). But for my entire career I have been working with computers and mostly programming or otherwise being involved in the building of software.
I think I’m pretty good at that now.
