I design interfaces for products where the AI is the primary actor and the UI supports oversight. From autonomous systems to data-heavy operator dashboards to AI-driven content platforms, I make complex software feel simple and controllable.
7+ years across B2B SaaS, AI products, and enterprise software. I've led design teams (4 designers, 2 researchers) and work just as comfortably as a senior IC. Previously shaped products across marketplaces, health tech, and consumer platforms on desktop and mobile.
