About me and my work

I am a Senior Product Designer at Bitly, based in Berlin. Over the past six years I have worked across B2B SaaS platforms, consumer products, and early-stage proofs of concept, designing interfaces that hold up under real use rather than only in a presentation.

My work spans the full product cycle, from early research and problem framing through user journeys, wireframes, and high-fidelity prototypes in Figma. I lean on research and product data to decide what to build, and treat accessibility and responsive behaviour as part of the design rather than a later pass.

I work closely with engineers, product managers, and researchers, and I care about leaving a team better organised than I found it: clearer design systems, shared vocabulary, and decisions that are documented well enough to survive turnover.

The selected work on this site covers design systems, management consoles, and mobile products. If you would like to talk about a role or a project, I would be glad to hear from you.
