Hi, I’m David.
Product designer and UX engineer, studying informatics and human-computer interaction at the University of Iowa. Most recently UI/UX engineering at Sollo in Tokyo, where I merged 70+ pull requests in eight weeks across design, mobile frontend and Python backend.
My own app, in testing
My own phone app for truck drivers who own their one truck: every load as one record, from saved to paid.
Trucking is the work I grew up around. I design and build it on my own: 5,888 tests and 144 merged pull requests so far.
Internship, shipped to the App Store
Eight weeks in Tokyo on an app that helps foreign residents of Japan through government paperwork.
70+ pull requests merged, the navigation redesigned, and every string shipped in nine languages. It is on the App Store.
Research, then a working app
A web app for students who commute to campus, built from five interviews.
I ran the research, designed it and built it, and one student’s answer changed what it became.
React and TypeScript, no UI library
Accessible components in React and TypeScript, with no UI library.
One token file themes every piece, and every control works by keyboard. Put the mouse down and try it.
The interchange every project runs through
Claude draws the options I choose between and checks the work against rules I wrote.
The decisions stay mine, and nothing merges without my word.

I study informatics at the University of Iowa, human-computer interaction, with minors in Spanish and psychology. Almost everything I build is for someone operating inside a language or a system that was not designed with them in mind.
The design half of my training asks who is on the other side of the screen. The engineering half means I can build the answer rather than hand it off.
