About
Design is a
decision problem.
I'm a UX/UI Designer based in Portland, OR. I work from research through prototype — focused on clear problem framing, evidence-based decisions, and design that holds up under real constraints.
My work spans consumer apps, e-commerce, and travel. Beyond screens, I care about the systems underneath — interaction patterns, information architecture, accessibility, and the handoff details that make or break implementation.

How I work
I start with the problem before opening Figma. Research shapes the brief; the brief shapes the structure; the structure shapes the interface — in that order. The decisions that matter most happen before the first frame.
