I’m a product designer who feels at home in a design file and a codebase.
For more than seven years, I’ve worked across product design, interaction design and front-end development. I’m drawn to complex systems: understanding the people, the constraints, and the details that make an interface useful.
At H&M, I work across internal planning tools and an enterprise design system. I also help the design team build working prototypes with Claude and Figma MCP, bringing ideas closer to implementation.
