Message

I am a Procurement professional with 10+ years of experience across Purchasing, Supplier Management, Contract Management and Source-to-Pay operations in multinational environments.

My career has given me experience across different sides of Procurement. I started with hands-on purchasing activities, including RFQs, competitive bidding, quotation analysis, supplier selection, purchase order management and supplier performance. Over the past years, I have developed extensive experience supporting Sourcing and Category Management teams through purchasing agreement management, commercial-condition analysis, procurement automation and process improvement.

Currently working in an international environment across EMEA, I bring experience from the Americas and Europe, combined with a strong SAP and procurement process background. I have also contributed to global transformation initiatives involving S/4HANA/Fiori, procurement automation, functional testing, process design and knowledge transfer.

I am particularly interested in Strategic Procurement and Category Management opportunities where I can combine my purchasing background, supplier-facing experience and deep understanding of downstream procurement operations.
