Description

Tech Lead & Power BI / Microsoft Fabric expert, I manage the governance and administration of large-scale BI platforms — from workspace architecture to semantic model optimization for 5 to 100 million rows.

My role extends beyond technical expertise: I serve as the cross-functional point of contact for business teams, data engineers, and architects, and I train teams on Power BI (levels 1 & 2), with over 2,000 employees trained in Paris and Amsterdam, in both French and English.

I am currently integrating GenAI into the BI workflow (Copilot, MCP, LLM orchestration) to industrialize and ensure the reliability of data production.

Power BI & Microsoft Fabric Tech Lead, I own the governance and administration of enterprise-scale BI platforms — from workspace architecture to tuning semantic models ranging from 5 to 100 million rows.

My work goes well beyond the technical side. I’m the cross-functional point of contact for business teams, data engineers and architects, and I train teams on Power BI at both beginner and advanced levels — 2,000+ people trained across Paris and Amsterdam, in French and English.

I’m now embedding GenAI into the BI workflow (Copilot, MCP, LLM orchestration) to industrialize and harden data delivery — a space I also explore as founder of Ultima (ultimai.app).

8+ years of experience, from startups to CAC40 leaders: Air France-KLM, Safran, Crédit Agricole, Europe Assistance, Renault Group
