Freelancer profile translated to English.

Description

You have the data. You lack readability.

**10 years of Power BI consulting**, I help management and business teams transform their data into reliable, readable, and maintainable reports over time.

I intervene end-to-end: from connecting to your sources to production deployment, with constant attention to model quality and end-user experience.

What I do concretely:

Data connection and transformation (ERP, CRM, SQL, API, Excel/CSV)
Semantic modeling and DAX development
Power BI dashboard design (from mock-up to deployment)
Audit and optimization of existing models (performance, readability, KPI consistency)
Automation of refreshes (gateway, Power BI Service)

Accustomed to **large corporate and SME environments**, I understand the challenges on both sides: robust models that don't break, and dashboards that your teams actually open.

I work fully remotely with teams in France, with structured exchanges and documentation delivered at each stage.

Available quickly. Feel free to contact me to discuss your needs.
