Speaking and teaching

Since 2010 I have taught more than 150 sessions to over 5,000 people, at every company I have worked for and at more than 25 colleges. I teach what I practice: writing software that lasts, measuring delivery honestly, and using AI responsibly in regulated engineering.

150+

talks, workshops and training sessions since 2010

At IBM, Exeter, Amazon and Philips, and at more than 25 colleges.

AI in regulated engineering
Using AI for requirements, traceability and testing under IEC 62304, with people making the final call.
Engineering flow
DORA metrics and continuous value delivery as a management tool, not a scoreboard.
Craftsmanship and quality
Quality gates at the developer desk, technical debt you can see, and design that lasts.
