Slate

A private journal that stays on your device. Designed, built, and operated solo.

  • Grew to 750+ paying customers across 82 countries.
  • Converted approximately 31% of completed free trials into paying customers.

Rams

Design and accessibility review for developers, built into the way they ship.

  • Delivered 7,700+ design and accessibility reviews across 4,000 repositories.

HSLA0001

My independent studio behind Slate, Rams, and my other software.

  • Build and operate a portfolio spanning consumer apps, developer tools, subscriptions, and one-time purchases.
  • Created Framework: four focused apps for writing, focus, and habits, each built around a single daily practice.
  • Shipped Autobahn, an open-source kanban board that turns markdown files into a working project board.

Sessions

I also work with a small number of founders in focused sessions on decisions that shape their product.

What should you ship? Where does the purchase flow break down? Is an idea worth another month of development?
