About

25 years building data platforms. Now applying that discipline to AI.

Data solution architect — metadata-driven platforms, knowledge architecture, and AI. I’ve spent my career making data trustworthy for institutions where reliability isn’t optional. These days I point that same discipline at the AI layer.

What sets my work apart is a strong business focus. Good models start with the business, not the database — a conviction sharpened by Alec Sharp’s business-oriented data modeling. I translate what the business actually means into structure a machine can rely on. That bridge — business meaning to reliable structure — is the whole job.

Beyond formal architecture, I tend to play innovation catalyst and architectural evangelist: introducing new ideas, challenging existing patterns, and turning concepts into practical frameworks teams can actually adopt. My current conviction — the future of data architecture is metadata-driven, automated and knowledge-centric.

Selected work

Proof, not slides.

My flagship: leading the model-driven data warehouse at de Volksbank & ASN — where MDDE was built — plus a signature SQL-migration engagement proven identical with CTE-by-CTE regression testing. I also founded and run the MDDE meetup (4.6★, 52 reviews), and the work has been covered in the trade press.

CTE-by-CTE regression testing pinpoints which transformation step diverged — How I de-risk migrations: compare step by step, find the root cause — ~10× faster.

Standing on good shoulders

Influences & collaborators.

My approach is built on decades of thinking by people who shaped how we model, historize and govern data — from Hultgren, Roelant Vos and Alec Sharp to Inmon, Kimball and Len Silverston — plus collaborators I’ve built real things with, like CrossBreeze.

Beyond work

Curious by default.

I draw inspiration from science, technology, design and the arts — from contemporary dance and opera to hiking and travel. That broad perspective is, I think, part of how I approach complex data problems: look for the pattern, find the structure, keep a sense of craft.
