About

I started building websites as a teenager, then went on to study games technology. Since then I’ve built mixed-reality training software, worked on indie game projects, and now teach the next generation of developers.

My teaching is practical: Python, databases and data modelling, web, mobile and IT security, taught the way they’re used in industry.

As Programme Leader I also help design the curriculum and look after the department’s data, so results, deadlines and feedback stay accurate and on time.
