Back to original languageAbout Frantz
I support business, finance, and operational management in implementing reliable and actionable decision support systems.
As an expert in Power BI & Azure (ADF, SQL), I work on data structuring, reporting automation, and strategic indicator definition projects, in demanding and often regulated environments.
My approach is focused on usage and business impact: less Excel, reliable data by D+1, a clear vision to decide faster.
I provide expertise in both upstream consulting (needs, indicators, governance) and operational implementation (modeling, automation, dashboards).
