Popular work

I once made a cell phone out of resistors, capacitors, walnut, and leather.
Finda is a super-fast, super-opinionated desktop search app to end the tyranny of GUI windows, tabs, and useless hierarchy
Subform was a UI design tool I built with Ryan Lucas and 1,000 Kickstarter friends. See my “Choosing features” talk for how how we applied conceptual design to build an accessible layout engine.

Please get in touch!

I love to hear from people, especially if I can help with their projects or careers! Please email me if you:

are interested in collaborating (check out my list of open ideas)
want more details about any of my projects (tech implementation, business strategy, etc.)
would like an introduction to someone (e.g. visualization/statistics, functional programming, or software design experts; investors in those domains)
want feedback on something you’re making

If you think it’s weird to email people you don’t know — it’s not! Some of the best relationships I have, business and personal, started when one of us reached out to the other for help on a project, thoughts on a problem, or just coffee! So, if you’re considering emailing, please do it!

For best results, see Patrick McKenzie’s tips for emailing busy people.
