About Sothalen

With over 15 years of experience in management control, budget management, and financial transformation for large corporations (banking, CAC40), I bring a 360° vision connecting Finance, IT, and performance management.

Proven ability to manage projects independently or lead mixed teams (internal + external consultants) in complex and regulated environments.

Key expertise:
- Strategic definition and deployment of unified EPM solutions (Tagetik AIH/CPM)
- Optimization of closing, budgeting, forecasting (driver-based models, rolling forecasts, process redesign)
- Support for Financial Departments on complex issues (outsourcing projects, Finance IT transformation)

Notable achievements:
- Multi-deployments of Tagetik AIH/CPM in banking (advanced modeling, agile forecasting)
- Structuring projects at Dexia, Orange Bank, BNPP: budget process redesign, FP&A outsourcing, driver-based & rolling forecast implementation
Autonomous throughout the entire cycle: agile scoping, SFG, POC, functional acceptance, user training, project governance.

Open to senior freelance assignments in partnership with consulting firms (Big 4, premium IT service companies, e.g., EY, PwC) to integrate their systems and participate in Finance IT transformations
