Profile

eLearning developer with over 15 years at UK agencies and as a freelancer, across graphic design, development, instructional design and consultancy. I've built hundreds of modules for organisations including HSBC, PwC, Deutsche Bank, Lloyds, Save the Children and Triumph, as part of large global teams and end to end on my own.

Lately I design and build my own products too, all hands-on: AI Data Guardian, a gamified AI security awareness course, and a browser-based 3D simulation of EV high-voltage safe isolation. I build with AI-assisted development, which lets one developer ship what used to take a team, with automated testing on every change.
