About Sébastien

Through my experiences in consulting firms and companies, I manage high-impact business data and customer insights projects, from the scoping phase to operational deployment.
I combine project leadership with direct operational contribution to analyses, intervening myself in data exploitation (SQL, analysis, segmentation) and insight production when necessary. This approach allows me to ensure a strong link between strategy, execution, and the quality of deliverables.
I support business departments (Marketing, Sales, Finance, IT) in transforming their data into concrete performance levers, by structuring needs, aligning stakeholders, and securing project execution.
Accustomed to working in complex and cross-functional environments, I combine strategic vision, operational management, and data expertise to deliver actionable and measurable solutions.
