🧠 “Architecture doesn’t fail in the codebase. It fails in the meeting rooms.”
My latest piece on @InfoQ explores why broken systems often reflect broken communication - not bad tech.

#SoftwareArchitecture
If AI writes the code, where does the next senior engineer come from?
I think that's the wrong question.
Perhaps AI isn't only changing how engineers become experts. Perhaps it is changing what an expert is.

If AI writes the code,
why do we still measure quality in code?
In the AI era, quality lives in
architecture, constraints, and governance.

#KeycloakDevDay 2026 today! 🔑
I’ll be speaking at 15:30 in Room Private Bar about
“From Pods to Permissions: Token Exchange Meets Kubernetes Service Identity.”
Looking forward to discussing Kubernetes & Keycloak service identity patterns with the community.
When execution stops being the constraint, structure becomes visible.
Teams, workflows, and governance suddenly matter - a lot!
I tried to write about that shift.

#SoftwareArchitecture rarely fails in code! It fails in meeting rooms, handoffs, & the silences between teams. The hardest bugs aren't in technical, they're in communication.
The Technical is inseparable from the Social.

Most service-to-service auth in platforms is broken by design.
In my new article, I show how to solve this properly using Keycloak’s Token Exchange - with real-world scenarios and a clear architectural approach.
