About Rosy

Senior Management Controller, I support SMEs, startups, and firms in structuring and digitizing their financial management to move from reactive management to proactive decision-making.

I work across the entire financial steering chain:
  • Structuring and validating financial data
  • Implementing decision-making dashboards (Power BI)
  • Automating reporting and management processes
  • Deploying proactive alerts (cash flow, margin, inventory, performance)
Objective:**give leaders a clear, reliable, and actionable view of their business,** without relying on time-consuming manual files.

🔹My Approach
  • Profitability and decision-oriented management control
  • Business Intelligence applied to business challenges
  • Automation to reduce low-value-added tasks
  • Preventive rather than curative steering
🔹Results for My Clients
  • Reliable financial tracking without re-entry
  • Significant time savings for teams
  • Anticipation of operational risks (cash, margin, inventory)
  • Faster and more secure decisions
