I’m a programmer, speaker and activist. I seek deep understanding
so I can create clear explanations.
Recreating Sketchpad, the first GUI was a talk at !!con 2024 about what we can learn by studying and rebuilding early user interfaces. Earlier, Constraint programming in the browser at JSConf 2013 covered related ground, alongside a short note on being inspired by Sketchpad and its constraint-oriented UI.

Synchronizable abstractions for understandable concurrency is an explanation of the Concurrent ML event system — the small, careful design that later inspired React Fiber.

The companion Preact Internals series goes deeper. Earlier, in 2014, I gave an early talk on React + Om and wrote an experience report on shipping a ClojureScript wrapper for React.

From 2011–2017, I primarily worked on in-browser WYSIWYG design tools for websites and images.
A more complete chronological account lives on my LinkedIn profile.
Open-source and volunteer work — small collaborations that tend to outlast the season I spent on them.
Read Japanese Literature is a podcast and blog run by my partner, Alison. I help with the website and sound design.

Federated Wiki is a new, personal version of the wiki being developed by Ward Cunningham. In 2011, I collaborated with him to design and build the core UI paradigm that still powers it today.■
