04 — Off the Clock

I like problems with a real, annoying edge - and ending them with something shipped.

I'm a full-stack engineer based in Portland, OR. A care facility still on paper charts, a job hunt buried in spreadsheets - those are the kinds of things I like to take apart and rebuild. I care about the whole arc: the interface someone touches, the API behind it, and the AWS infrastructure keeping it up at 3am.

Off the clock you'll find me away from a screen - outdoors around the Pacific Northwest, behind a camera, or chasing a better cup of coffee.
