Freelancer profile translated to English.
Back to original language
HR/HRIS Data Analyst with a rare dual expertise: I speak the language of HR managers and IT teams.
At EDF Power Solutions, I automated a critical payroll process—from 4 hours to 3 minutes. I designed Power BI dashboards presented to the Executive Committee and developed a Power Apps application validated in production.
I master the HRIS market ecosystem: Altays, Cegedim, Expensya. I work across the entire chain: collection, modeling, visualization, and automation of HR data.
