About Me.
I’m an award winning product leader and consultant with 12+ years across Banking, Big Tech, Pharmaceuticals, and UK Government.
I build products from 0→1, turn around legacy platforms, and lead organisational change. I care about outcomes, not outputs.
Deep expertise in AI powered products, from the UK Government's first AI fraud engine to brain scan quantification, leading multidisciplinary agile teams from backlog to boardrooms.
I’m now back in Newcastle after a five month break travelling Australia and New Zealand, and I’m available immediately for my next role.

What I shipped in Scroll Books' first weeks live in the stores: the compliance grind, a dependency reckoning, humbling retention data, and why I killed streaks.

My Beliefs.
- AI is a collaborator, not a vending machine
- Share the embarrassing first version, don’t ship it
- Product includes the work of deciding what not to build
- Fall in love with the problem, not the solution
- The interesting work happens at the edges
