BIO
I'm a self-taught software engineer with a generalist's background and a penchant for collecting experiences. I've worked as a builder, a mechanic, a gardener, and an organic farmer, but I've spent most of the past 25 years developing software and running software teams in Silicon Valley. A former early hire at startups in cleantech, food, and aerospace, I also have over a decade of combined experience at two of the largest technology companies in the world: Apple and Google.
