Profile

Product designer with six years of experience in technology and a foundation in UX research. I take products from discovery to developer handoff and am strongest on complex, technical products. My background includes four years designing cloud-infrastructure tools for developers and my current work on consumer fitness products in Amsterdam. I use research evidence to guide design decisions, and I build AI-queryable research repositories and automated feedback pipelines that keep product teams connected to user data.
