Founder, product, and design conversations where AI behavior and product clarity both matter.

I’m a founder, product designer, and operator with experience across startups, enterprise software, and venture-backed teams.

Over the last decade I’ve worked across consumer, fintech, SaaS, and AI products, helping teams move from early ideas to clearer products, stronger systems, and more decisive execution.

Right now I’m focused on products at the intersection of AI, trust, wellness, and human-centered technology.
