With over 20 years of experience in large corporate environments, I work on high-stakes HRIS programs related to payroll, time management (GTA), and Core HR, from scoping to operational stabilization.

My expertise is based on a dual functional and technical skill set, enabling effective alignment between HR, IT, and vendors to secure processes and ensure data reliability.

I have notably managed environments integrating SuccessFactors (Talent & Performance), Meta4, Chronogestor, and PeopleDoc, with full responsibility for:

project governance and multi-stakeholder coordination

steering testing phases and analyzing functional discrepancies

managing the Run and continuous process improvement

At Veolia (14,000 payrolls), I contributed to structuring Build & Run frameworks, ensuring payroll cycle reliability, and improving support quality by controlling operational indicators.

My approach is based on continuous improvement principles (Lean / DMAIC): clarifying processes, analyzing discrepancies from tests and acceptance, and establishing sustainable standards to stabilize systems over time.

Beyond technical skills, I bring a posture based on listening, analytical rigor, and team cooperation to build effective and lasting solutions.

I primarily focus on:

HRIS transformation and deployment

Payroll & GTA expertise
