Freelancer profile translated to English.

Description

Most companies accumulate data without truly understanding what it says, and their decisions are often based on perceptions rather than facts. This is exactly where I come in.

AI & Data Science Engineer (CESI Strasbourg), I spent six months as a Business Intelligence Engineer at Amazon Europe Core in Luxembourg, where I designed critical pan-European ETL pipelines, optimized SQL queries on Redshift, and deployed QuickSight dashboards for multi-site teams with diverse needs. At MyFood, I single-handedly managed the complete migration of the information system, from modeling to production. In parallel, I work as an independent consultant for SMEs and scale-ups, focusing on data structuring, Power BI dashboards, reporting automation, and IT system audits.

What guides each of my missions: starting from the actual business need, not the technical stack, and delivering documented and maintainable deliverables, not a dashboard that no one understands three weeks later.

Available 3 to 4 days a week, full remote (France, Luxembourg, Belgium, Switzerland) or hybrid in the Grand Est region, or occasional on-site work in Luxembourg. Bilingual French/English.

Typical deliverables: Power BI and QuickSight dashboards, Python/SQL ETL pipelines, reporting automation, data modeling and auditing, Odoo CRM administration, decision support analyses.
