Designing and building interfaces for agentic systems.

Currently leading product design at Extend — a B2B fintech building virtual cards and expense workflows, where I'm shaping how agentic capabilities reach the surface. Previously shipped end-to-end product work at Lumi as both designer and engineer, including an open-source React component library. Long interest in the emerging patterns between people and agentic systems.
