Staff Product Designer
AI & Design Systems

Twenty-plus years in Silicon Valley, now home in London. A product designer who builds the system underneath the product, and the tooling that keeps AI-built UI on-system.

Most recently I led product design for an AI security operations platform, owned its design system, and built the tooling that checks AI-generated UI before it ships. Before that: PagerDuty, Palo Alto Networks, Sony, Samsung. Available now for Staff and Principal roles, London or remote.

// What I do
01

AI Product Design

Designing AI people can check before they trust: evidence, doubt and limits on every finding, and actions that say what they will change before anyone says yes.

  • Human in the loop01
  • Evidence and confidence UI02
  • Autonomy and approvals03
  • Agent workflows04

Design Systems

Systems that act as a floor, not a ceiling. Tokens, components and the governance that lets new ideas in without letting drift through.

  • Tokens and components01
  • Governance and contribution02
  • Accessibility03
  • Dark and light theming04

Design-to-Code Tooling

The step between "someone generated a screen" and "it ships". Checks, snaps and typed gaps, built in code with AI agents.

  • Claude Code workflows02
  • Prototyping in code03
  • React and React Native04

Brand and Visual Systems

Twenty years of craft, from Strikeforce to PagerDuty: brand refreshes, an NYSE IPO launch and four Summit conferences.

  • Launch and IPO packages02

CRNCH: make credit boring

My own iOS app, zero to one: product, brand, design system and React Native code, built with AI agents working inside the system.

The governance loopAn idea is generated by a person or an AI tool, then checked against the kit. On-system work snaps to the system and ships. Anything new files a typed gap, a designer makes the UX decision, it becomes a real component, and it goes back into the kit that future checks use.IdeaGenerateperson or AI toolCheckagainst the kitThe kitparts, coloursSnap to systemthen it shipsFile a gaptyped, visibleUX decisiona designer calls itReal componentfitsnewback into the kit

Keeping AI-generated UI on-system

The governance step that checks every screen against the design system before it ships, whoever or whatever made it.

AI that shows its working

How an AI shows its evidence, its doubt and its limits, and why autonomy follows reversibility. Full case study coming soon.

// Principles
01/04
New is never a failure. Undeclared is.
A design system should be a floor, not a ceiling.
A passing check proves the parts. It can't prove the screen is good.
That part stays with designers. Good tooling gives them more time for it.
AI makes a plausible analysis cheap. Checking it is the job.
From "Being wrong in public", a field note.
If it needs a walkthrough, it isn't finished.
Plain language for PMs, designers and engineers alike.
