Alex Garnett is Senior Technical Curriculum Developer, Temporal; prior to that, he was Senior Technical Writer at DigitalOcean, and before that, he was a digital archivist, working with analog film transfers and learning more obscure ffmpeg features than most people (except this guy: https://www.youtube.com/watch?v=9kaIXkImCAM) would ever want to. He became a writer and editor to save them the trouble.
