About

Senior UX/UI Designer with 15 years across product strategy, UX/UI, and design systems. I turn rough product ideas into shipped interfaces in days—not weeks—using AI and no-code tools such as Lovable, Webflow, and Wix to reduce handoffs and accelerate delivery. At Toptal, I work as an end-to-end design partner for US and European startups, covering research, UX, UI, functional prototyping, and technical execution. At Reneo Group, my work on its decarbonization platform supported a €600M capital platform, including a joint venture with Peakside Capital to deploy around €500M. Earlier, I built Exactaworks’ UX function from scratch and led a brand redesign that increased recognition by 30%. Based in Hamburg, I partner with founders and product teams that need design delivered at startup speed.
