Hacker, maker of things

I’m happiest in a place that respects
kindness, enthusiasm, and individuality,
doing many kinds of work,
(mostly writing internet software,
but also design, writing, & leadership),
serving a clear and inspiring goal
that creates more value for others than ourselves.


Senior Software Engineer / DevOps, March 2018 – June 2024

Scaled VRChat from a meme to a community of millions. As a very early employee, in a flat to no-hierarchy organization, I've created or worked on nearly every backend system, often coordinating with other teams to deliver features. VRChat has to process millions of user-submitted 3D assets and that was my focus area for the last few years – architecting, coding and deploying the backends of our big swing projects. I usually also delivered the web UI for my own features, and it was often praised for its usability. As a side project, dramatically simplified our test code and reduced time-to-deploy from almost an hour to minutes.
