About

TABULAR

TABULAR empowers you to build human connections, making it possible to learn together how to develop elegant semantic models.

Elegance arises where simplicity, efficiency and effectiveness intersect.

Reducing complexity is the foundation of maintainability, making your code easier to understand, easier to modify, and easier to test. Knowing how to apply the right tools and methods will save you valuable time. Ultimately, you want your model to enable decision‑making that leads to a positive impact.

TABULAR since 2015

I founded TABULAR more than a decade ago and worked with enterprise clients like PwC, ABN AMRO, Allego, KPMG and KPN.

Continuous learning is part of my DNA. Attending community conferences has simply become part of what I do. We master knowledge by passing it on.
