Portfolio — Head of UX // 20+ YRS EXPERIENCE
I'm Clifton Green — a practitioner-leader who builds enterprise UX at scale.
AI agents. Design systems. Research that moves decisions.
Senior enough to see the horizon. Still close enough to write the code.
02 / Selected Work
Case studies across AI, design systems, research, and interaction design. Each one with a clear problem, a deliberate pivot, and measurable outcomes.
100+ component enterprise system spanning UI, brand language, photography, and tone of voice — with a production React library still live today.
An AI agent that transforms source documents into production-ready ServiceNow knowledge articles — powered by a 29-component JS-free design library built from scratch.
174-response mixed-methods Maze programme across UK, India and US. Key finding resolved a contested navigation decision with unambiguous evidence.
Conceived, named and built before AI existed to do it. Still live on easyjet.com — nine years later. A second product built directly from the same concept launched in 2024.
03 / About
20+ years building experiences for real people — energy traders, online gamblers, 98,000 bank colleagues trying to book annual leave without wanting to quit their job.
I think in systems but sweat the details. I write production CSS. I run research. I present to MDs and sit with developers in the weeds in the same week. The best design leaders never fully leave the craft behind.
Looking for somewhere I can build something genuinely meaningful at scale.
