Senior SAP Project & Program Director | 20+ Years | Global Transformation | S/4HANA | AI
I bring 20+ years of experience delivering large-scale SAP and digital transformation programs as Senior Project Manager, Program Director, and Interim Manager across Western Europe, DACH, EMEA, MENA, and GCC.
Throughout my career I have progressed from Project Manager to Senior Program & Consulting Director, leading business-critical ERP, CRM, ITSM, and SAP S/4HANA Greenfield & migration programs for leading enterprises across manufacturing, logistics, finance, PLM, and regulated industries — including government.
Delivery & Program Management I have successfully managed programs exceeding $100M in budget with teams of 200+ people, ensuring on-time, on-budget delivery with full financial accountability. I define and enforce corporate delivery frameworks, governance structures, and escalation models that keep complex programs on track across multiple workstreams and vendors.
Vendor & Stakeholder Management I have built and maintained strong C-Level relationships internationally, leading steering committees and executive reviews across diverse geographies and cultures. My vendor management expertise covers contract negotiation, SLA definition and enforcement, and multi-vendor coordination in outsourcing and transformation contexts.
Interim Management I have served in multiple interim roles as Project Director, Program Manager, and Consulting Lead — stepping into critical situations, stabilizing delivery, and establishing sustainable operating models within short timeframes.
AI & Innovation Certified Anthropic Claude AI Engineer and official Anthropic Implementation & Consulting Partner. I integrate AI tooling into project delivery, contract analysis, and consulting workflows, with a clear understanding of capabilities, risks, and boundaries.
My international exposure across cultures, industries, and regulatory environments has shaped a leadership style that is results-driven, adaptive, and trusted at the highest organizational levels.
