This site is all about my work as an executive coach and consulting Chief Technology Officer (CTO). Using my 15 years of experience as a senior technical leader - and a set of clever management techniques called Action Science - I help companies of all sizes make big changes to their culture, skills, and processes. I provide transformation and advisory services, deliver courses and talks, and offer free help to startups. To learn more, you can watch me in action, check out my biography, or read a case study.

When Squirrel began working with us, the engineering team was full of talented and committed developers who lacked leadership and confidence. He helped to transform them into an energised, highly-focused team who now deliver high-quality product better and faster than I could have imagined.
