Hi, I’m David.
I’m a product designer and UX engineer. I study informatics (HCI) at the University of Iowa and graduate in May 2027. I take a product from the first sketch in Figma to the code that ships.
My own app, in testing
A phone app for truck drivers who own one truck. Every load is one record, from the day it’s booked to the day it’s paid.
5,888 tests and 144 merged pull requests, and I design and build it on my own. I grew up around trucking. The paperwork is the hardest part of the job, so that’s what this app takes on.
Internship, shipped to the App Store
Eight weeks in Tokyo on an app that helps foreign residents of Japan with government paperwork. It’s on the App Store.
70+ pull requests merged, nine languages shipped. I redesigned the navigation and shipped every string in nine languages, because the people using it don’t all read Japanese.
Research, then a working app
A web app that helps commuter students find events and each other on campus.
5 interviews, 3 findings, 1 answer that changed the design. Campus apps are built for students who live there, and commuters get left out. I talked to them, designed it and built it.
The AI assistant in every project
I’m one person doing the design and the code, so I use Claude, an AI assistant, as a second set of eyes.
It lays out the options side by side and checks the work against rules I wrote. I pick, and nothing goes live until I approve it.
Tap to learn more about how I work with Claude
I study informatics at the University of Iowa, focused on human-computer interaction, with minors in Spanish and psychology. Most of what I build is for people stuck in a language or a system that wasn’t made for them.
Design taught me to ask who’s on the other side of the screen. Engineering lets me build the answer myself. I learned both so nothing gets lost between the design and what ships.
