Back to original languageAbout Sebastien
After 15 years leading profitability, development, and strategy for complex B2B projects, I now help business departments leverage their data assets. My strength? A dual business and technical background. I master the modern data stack (SQL, Python, dbt) to structure your data, and I use my business acumen to create decision-support dashboards (Power BI) that truly resonate with your teams. My goal: transform your raw data into growth drivers.
