Over 15 years designing digital products from scratch and leading small teams. The last four focused on AI — working across the full journey from early concept to production, in companies ranging from early-stage startup to enterprise. And I don't just design AI products, I build with it: working prototypes in code, not just Figma.

I started in software development and graphic design, and moved into product design over time. Most of my work has been in startups and scale-ups as well as large corporate companies, covering everything from early research through to shipped product.

My recent work has been AI-native products: a Webby-recognised AI tourism platform and a clinical AI system at Scale AI, Head of Design at BLKBOX.ai, and founding designer at Briefly, which reached 5,000 customers in its first year. My job is making complex systems legible to the people who use them, and I prototype in working code with AI-assisted development, so ideas get validated as real, interactive builds rather than static mockups.

Capabilities

01

AI Product Design

End-to-end design for AI-powered platforms. Translating complex system behaviour into interfaces people can actually use and trust.

02

AI Prototyping

Working prototypes built in code with AI-assisted development. Real, testable products instead of static mockups, validating ideas faster.

03

0 → 1 Products

Taking products from first research to shipped experience. Comfortable with ambiguity, and with the particular pressure of early-stage work.

04

Design Systems

Building scalable component libraries and token-based systems. Useful for teams that want consistency without slowing down.
