The journey.
Co-founder of Key User Training. Independent SAP consultant, EWM certified, specialized in Supply Chain and S/4HANA architecture.
Before SAP, eight years in industrial maintenance at Ceratizit: maintenance methods planner, team lead, then methods manager. His first real contact with SAP came in 2018, as a key user on an ERP implementation project on the maintenance side. In 2020, he moved into the SAP Logistics consultant role, still at Ceratizit, working mainly in-house on S/4HANA and EWM. Since founding Key User Training in 2022, he has also taken on occasional external assignments. It is this key-user experience that grounds his teaching.
Official author on the Espresso Tutorials platform, where his SAP EWM and Supply Chain courses have supported thousands of learners in French and English. He also runs the MIX SAP newsletter (2200 subscribers), a weekly share of field insights for key users and consultants in the making.
His conviction: you learn SAP through hands-on practice on real cases, not from the documentation. And the best SAP consultant is first and foremost a consultant who understands the client's business.
