Featured work

Projects

A mix of professional systems, independent software, games, and coding demos.Systems, software, games, demos and more.

I have more work than I can reasonably show on one page. My GitHub profile includes a broader selection of publicly available projects, and I am continuing to add fuller writeups here. The projects below are the ones I have documented so far. Much of my professional work is not public, but I am happy to discuss it in an interview or other professional setting.

About

Engineer, builder, and problem solver.

I’ve worked on high-scale enterprise systems, independent SaaS-style software, creative technical projects, and games. I care about clean architecture, practical interfaces, stable systems, and software that people can actually use.

Outside of software, I build and repair things, work on a small homestead, play bass, make art in many mediums, and perform with various groups.
