What I'm looking for

I’m looking for a role where I can own global materials planning, drive KPI improvements, and strengthen supplier resilience—combining forecasting, MRP-driven execution, and cost optimization with continuous process and data system improvement.

I’m a “Manager, Global Material Planning” at Moderna, with additional ownership for supplier portfolio resilience planning and continuous KPI improvement. I focus on mid to long term planning analysis and decision making, including cost optimization and planning system data maintenance and improvement.

Previously as “Sr. Specialist, Materials Planner / Buyer” at Moderna, I owned demand planning and forecasting, supplier management, and end-to-end purchase order management (from issuance to closure incl. GR/IR). I also handled inventory control, MRP results rework, line-up demands, invoice resolution, and shipment tracking through to CMO with GR reconciliation and exception management.

Earlier roles strengthened my end-to-end operations and process mindset—from supply chain management and ISO quality compliance at Tallamar Electronics, to procurement process implementation and support at Robert Bosch, and finance/risk work including accounts payable, accounts reconciliation, and credit risk assessment. I’m known for strong ownership and accountability, analytical attention to detail, and efficiency under pressure in fast-paced supply chain environments.
