Consulting · core focus

I build BI systems your decisions can rely on.

I work on both planes — the strategic advice that sets direction, and the engineering that builds it — with teams who want solutions that survive real use, not a demo that falls apart the moment real data arrives.

About

An engineer who teaches what he builds.

For over fifteen years I have worked at the intersection of data, software, and BI — from pipelines and migrations to Power BI solutions used daily by real teams. Software engineer by training, BI consultant by trade. I work with companies in New York and across Europe, run Plumgate, and consult and teach independently.

I believe in reports that tell the truth and AI that sticks to the facts. No embellishment, no invention — only what the data actually says.
