Projects

I enjoy building things that reveal how systems work and how to make them faster.

My side projects range from interpreters and compilers to game solvers, developer tools, databases, visualization tools, experimental filesystems, and web frameworks. My public GitHub repositories have been starred 1887 times. I continue to publish and share regularly and my last open source git push was 3 days ago.
