I'm Chief Scientist at proAgile Ltd. You could pretty much say that software engineering methodologies are my bag.
I specialize in agile transformations at enterprise scale, and tweet and blog quite actively about this. I'm also the curator at agilepatterns.org.
An agile consultant, I've worked as a Scrum Master for the Scottish Government, 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.
