About me

If you think hard enough, sometimes the work is easier.

Work

Payments

My primary work for the past six years has been building UIs and APIs for payments.

• <iframe>able finance was a talk about building embeddable web UIs for Fintech Devcon 2023.
• At Rainforest, I work on embeddable versions of the entire payments lifecycle.
• At Stripe, I worked on Elements, PaymentIntents, SCA, W3C / EMVCo, and emoji.

Thoughts

UI programming models

I believe it is still possible to improve how we work together to build UIs.

• State machines: Pure UI Control and What are the important problems in UI engineering?
• Concurrent ML: Synchronizable abstractions for understandable concurrency and Concurrent ML has a branding problem
• Constraint programming in the browser was a JSConf 2013 talk. See also Being inspired by Sketchpad and its constraint-oriented UI.

Web UI engineering

Preact in Pictures is a talk that explains the core virtual dom diffing algorithm. The Preact Internals series discusses helpers, the component model, and DOM diffing.

Types: I spent much of 2017 thinking about how types can help UI programming. I wrote up some now-old advice on ADTs and exhaustiveness.

The new fast was a talk on web performance techniques that were fairly new in 2017 thanks to new browser standards.

React/Om: I was an early adopter and (slight) contributor to React and Om, a ClojureScript wrapper for it. See my 2014 talk on React + Om (a ClojureScript wrapper for React) and a 2014 experience report on working with Om.

Projects

Open-source and volunteering

Read Japanese Literature is a podcast and blog run by my partner, Alison. I help with the website and sound design.

Pyret is an in-browser programming language and environment for use in the Bootstrap curriciulum. In 2020 and ’21, I updated their IDE to be shinier, faster, and easier to use.

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.
