DESIGN ENGINEER

I design it, build it, ship it.

I create enterprise systems by day and ship my own apps at night. I love working across the whole product, from figuring out how it should work to making it actually work.

Right now, I'm building at IEEE, shipping design critiques with Crit, and building a training tracker for martial artists with Tatami.

ABOUT ME

I've been a researcher, systems thinker, and builder, sometimes all three in the same afternoon. I can't leave a problem alone until it's actually solved, not just designed. 4+ years in, I still haven't figured out how to stop caring about the details. Probably not going to.

I run my life like a tracked system; nutrition, training, the work, all logged and questioned. I'm a research-driven designer who actually likes the friction. I'd rather be tested than flattered; tell me my assumption is wrong and I'll thank you. I build scalable systems, run real user research, and sweat the end-to-end details across web and mobile. Then I close the laptop and become the happiest guy on the dance floor.

I don't take myself too seriously. I go deep on the big stuff and stay goofy on the small stuff, sometimes in the same sentence. Both make the work better.

WHAT I DO

Mostly four things, and I'd rather show them than sell them. I design products end to end, the messy first idea through to something that actually ships. I turn one-off screens into design systems because I can't leave a pattern alone. I run the unglamorous kind of research, real interviews and testing, since I'd rather be wrong early than confident and wrong late. And lately what I hand off is working software instead of a picture of it, because a picture of a product and an actual product are not the same thing.
