I am Olivier Gemayel, a SAP Data Migration Project Manager with over two decades of experience helping large organizations move to SAP S/4HANA and modern data architectures. I excel in identifying functional requirements, scoping, and designing architectures; I combine technology and business insights to deliver data migration programs on time and within budget. I thrive in cross‑functional environments, guiding data governance, data quality, interfaces, and roadmap delivery across complex ERP landscapes. I lead diverse teams, manage data quality and governance, and implement interfaces and automations. My hands‑on expertise spans ABAP considerations, C#, LSMW, BAPI, SAP Cockpit, and MCO/maintenance of BI systems. I’m comfortable with AI‑assisted validation, RPA (UIPath), and advanced data validation, always aiming for traceability, documentation, and repeatable success across Development, QA, and Production environments.
