about me

I'm Catharina Börgert, a UX/UI designer based in Berlin.

I design digital products end to end — from research and user flows to wireframes and polished UI. For the last two years I've worked at BuildingMinds, where I help turn climate and ESG data into tools people can actually use. My main project, Proxima, is a sustainability platform for the real estate industry, and it was nominated for the UX Design Awards in 2026.

I care most about clarity. Complex data, dense dashboards, heavy workflows — my job is to make them feel calm, obvious, and human. I'm always learning through the Interaction Design Foundation and my own case studies, and I love working with teams that want design to have real purpose.
