18 years of experience in software engineering, distributed systems, and computer graphics. I am currently a Principal Software Engineer at Snowflake.Previously I was a Technical Director at Roblox, focused on Compute infrastructure and Observability. I have also served as full-stack CTO of CorePlane, a mobile app studio, and Battlehouse, a Y Combinator-funded MMO game startup.In my past career as a 3D graphics artist, I created Emmy Award-winning computer animation for National Geographic, PBS, and the BBC, and led the VES Award-winning visual effects team for the Walt Disney IMAX film "Roving Mars."My software tools have been used in the production of films and TV series including "Firefly" and "Battlestar Galactica."I've presented talks at Pixar, NASA/JPL, SIGGRAPH, the Motion Picture Academy, and PyCon on topics from 3D graphics pipelines to cloud devops for massively multi-player gaming.I've contributed code to many open-source projects, including the Linux kernel, FFmpeg, and React Native.
