WHAT KEVIN IS DOING NOW

I’m in Amsterdam, exploring:

 * optimization and generative geometry (in particular, autodifferentiation of
   signed distance fields)

 * digital fabrication techniques for furniture-making

Last updated: 2024 November 8.


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 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!
