View LinkedIn ProfileExecutive Overview
IT & Transformation Director | Executive Committee Member | Retail & Cooperative Networks For over 25 years, I’ve been leveraging IT as a powerful business driver. My playground: complex organizations, multi-site networks, and large-scale ERP projects. Today, within a major cooperative retail group, I lead IT transformation — a €40M annual budget, 12,500 users, 600 points of sale, and a clear direction: simplify, secure, and accelerate. Since 2021, I’ve been overseeing the deployment of SAP S/4HANA across the entire multi-brand network. A strategic, high-stakes program aimed at modernizing the core IT system, streamlining business processes, and boosting operational performance. What I enjoy: • Designing and managing robust, high-performing ERP organizations • Structuring governance and project prioritization (25/year) • Uniting teams around a shared vision, with both rigor and empathy • Turning technology into tangible value on the ground My strengths: • 25+ years of ERP experience (SAP) • Management of strategic programs (€100M+) and teams of 70+ people • Stabilization of complex IT systems and creation of ERP centers of excellence • Recognized leadership combining performance, stability, and quality Beyond the numbers, I deeply believe in collective success: listening, understanding, engaging. That’s how I work daily with over 500 member business leaders to build an IT system that serves shared success. Former CIO of Brico Dépôt (Kingfisher), I continue to blend strategic vision, operational excellence, and change management to drive lasting organizational transformation.
