What I've learned
Architecture is not the diagram. It is the story of how a team moves from idea to production - and how fast that story goes.
When delivery is slow, I look between the people first. That's usually where the weeks disappear.
The best problem is the one you don't have to solve. The best solution needs no explaining.
Retire the rules that no longer earn their keep, and automate the rest, so people's time goes to what matters.
I measure outcomes, not output.
Speaking
Conferences, meetups and writing about platform engineering, Kubernetes and the future of software delivery.
About
I’ve always been a builder. As systems grew more complex, I became just as interested in making them simpler.

More about meCurrent focus
I build systems where users express intent instead of navigating workflows. I combine AI agents with conventional software so the result is reliable, not just impressive.
