Projects

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

I have much more than this to show. My GitHub profile has a larger list of my publicly available work. I am working to add fuller project writeups here. In the meantime, please check out the projects I have documented below. A lot of my professional work is not public, but I am happy to discuss it in an interview or other professional context.

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.

Project managementLeadership, budgeting, hiring, accountability, mentoring, story creation, SLO definition, development, and execution.
Product ownershipRequirements, architecture, implementation, deployment, and iteration.
Broad knowledgeRetail, e-commerce, finance, healthcare, robotics, arts, and other areas of specialization.
