- Payment management, reminders, treasury updates
- Creation and updating of Excel spreadsheets
- HR and employee administration monitoring (holidays, absences, employee files)
- Payroll preparation or processing
- Filing, organization, and structuring of internal administration

✔️ My working method

Reliable, discreet, and very comfortable in family or artisanal environments, I easily adapt to working methods and bring clarity to internal procedures. I like to simplify, structure, and optimize to ensure everything runs smoothly.

✔️ Tools mastered

I can also create or improve your dashboards to facilitate your management.
