THE SHORT VERSION

I have been building interactive things for a living since 2000. It started in medical communications, went through brand and entertainment work for a while, and came back to medical, which is where most of it has stayed.

The short version is 25 years of interactive development, 15 of them in Unity, and about ten in medical XR specifically. Most of that was inside pharma agencies, latterly as Creative Technologist across IPG and McCann Health, where the job was as much working out whether a technology was ready as it was building with it.

I went freelance in 2026. I work with agencies and directly with clients, mostly on VR and AR training, congress and exhibition builds, WebGL interactives and AI integration. I am based in Cheshire, I work remotely for development, and I travel for on-site support at events.

What I am good at is the part between an idea and something that actually runs on the hardware in the room. I have shipped to Meta Quest, Apple Vision Pro, HoloLens, PICO, iPad and the browser, and I have stood on enough congress stands at eight in the morning to know what breaks.

Available for contract and freelance work at the moment.
