I liked computer games as a kid, and wanted to make my own. I heard computers are a good career too, so I went to university in computer science. Once I was there I realized writing operating systems was what I like the best. I like the challenge of it, and working close to the hardware. I do my best work in very complicated systems, because I’m good at keeping track of many details and making few mistakes. I want to do this sort of work moving forward, especially as long as I get to work on something lots of people will use.
