Software developer + dad based in Portland, Oregon. Past: Musician. Currently at Dropbox.

I'm a software engineer based in Portland, Oregon. I specialize in frontend development and enjoy component-based architecture, typography, and getting the details just right. I write a lot of TypeScript and React with a dash of Svelte and Astro on the side. I love building delightful, practical, and accessible user experiences that help people get things done. I currently work as a software engineer at Dropbox building the Forms application.
