About Jérôme

Are you spending more time preparing and cleaning your data than analyzing your results? Let's stop wasting time.

Hello, I'm Jérôme. I step in where ERP systems show their limitations. I help Financial and Operational Departments transform their time-consuming "Rube Goldberg machines" into automated, reliable, and connected processes.

My goal: to ensure your teams spend 80% of their time on analysis, not manual preparation.

What I implement for you:

- Workflow Automation (Power Query / VBA):
No more double entries and manual exports. I create intelligent gateways to connect your raw data directly to your analysis tools.

- Data Cleaning:
Automated processing of your "dirty" files (duplicates, formatting errors, outdated references) to ensure the reliability of your spreadsheets' source.

- Monitoring & Dashboards:
Design of custom dynamic Dashboards (financial, HR, sales KPIs). Your key figures updated in 1 click, without human error.

- Why choose me?
With nearly 14 years of corporate experience managing internal tools, I understand your business constraints before even discussing technicalities.

Let's discuss your next time-saving opportunity!

See you soon,
Jérôme
