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.

Public engagements

Speaking, writing & community.

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 me

Current focus

AI-native software systems.

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.
