I transform the finance functions of large corporations by leading the overhaul of their EPM and ERP systems (IBM Planning Analytics/TM1, Cognos Analytics, Power BI, Tagetik, Oracle HFM, SAP, Dynamics 365)—from requirements gathering through go-live.
I have over 10 years of experience at Servier, Société Générale, Orange, BNP Paribas, Airbus, and RATP, working on Finance & Procurement transformation programs, data governance, and process automation (R2R, FP&A, statutory consolidation, P2P, O2C, regulatory reporting).
What I do in practice:
→ I lead multi-site EPM programs in regulated environments (GxP, GDPR, IFRS)—from requirements definition to audit compliance
→ I automate financial workflows and standardize budgeting processes to reduce closing times and ensure data reliability
→ I build the capabilities of business teams to ensure adoption of new tools (training, user acceptance testing, L2/L3 support)
Recently developed expertise in AI applied to data governance and automation (Prompt Engineering, Data Engineering, Kubernetes/Cloud Native)—to bridge traditional finance challenges with new AI applications in the enterprise.
With a Ph.D. in Physics, I draw on strong analytical rigor to bridge the gap between business needs, governance constraints, and technology choices.
Open to projects involving finance/data transformation, AI governance, and cloud modernization across strategic, multi-entity programs.
