GitHub Sponsored OSS

Currently, I spend the majority of my spare time maintaining the following OSS, supported by GitHub Sponsors.

  • sqldef: Idempotent schema management for MySQL, PostgreSQL, and SQL Server.
  • xremap: Dynamic key remapper for X11 and Wayland
  • mitamae: A single-binary provisioning tool used to provision hundreds of production servers at my company.
  • pp: A colored pretty printer for the Go language.

Template Engines

I've authored or co-maintained some popular template engines. I also work on them in my spare time.

  • Haml: I authored the Haml 6 compiler and maintain it.
  • ERB: Ruby's default template engine. I made it 2x faster in Ruby 2.5.
  • Temple: The template engine framework used by Slim and Haml. I added two optimizers there.
