Hi there 👋 I'm David. I build cool stuff with Ruby on Rails and Hotwire, build engineering and product organizations, and write articles to help others build cool things, too.

In addition to my full-time job and my writing work, I sometimes work as a consultant for companies that align with my values. I'm available for short and long term consulting work to help your company:

  • Build Rails applications
  • Design and scale your engineering and product organization

On my own time, I'm working on:

  • Colby.so - My blog, where I write mostly about Rails and Hotwire, with the occasional diversion to broader engineering and product management topics when the mood strikes. Built with Jekyll and deployed on Netlify
  • Hotwiring Rails - A curated monthly newsletter on Rails on Hotwire. Powered by Buttondown
  • Hotwired ATS - A book on building a modern Ruby on Rails application with Hotwire and StimulusReflex, published on my own custom web application with purchasing powered by Gumroad. Rewrite for Turbo 8 publishing spring 2024.
