AI product builder, founder and operator.

I help founders and teams turn unclear AI ideas into scoped products, prototypes, internal tools and live MVPs.

My work sits across product, UX, technical architecture and build. I use coding agents to move quickly, but I care most about whether the thing being built is useful, testable and commercially sensible.

I am hands-on with modern full-stack tooling and agentic workflows, and I work remotely with founders and teams anywhere, with strong overlap with UK and European hours.
