I'm Chief Scientist at proAgile Ltd. You could pretty much say that software engineering methodologies are my thing.
I specialize in agile transformations at enterprise scale. I tweet and blog quite actively about this, as well as about Scrum, Kanban, and Agile development in general.
An agile consultant, I've worked as a Scrum Master and Agile Coach at the Open University, an Agile Transformation Coach at Travis Perkins, and I've been a Scrum Master at the NHS Information Centre, where I also coached on Agile transitioning. Before that I was a Scrum Master and Kanban Leader at O2 Telefonica. I've also assisted various Lean start-ups. I have a developer background.
