What I'm looking for

I seek a procurement role where I can lead process improvements, drive cost savings, ensure supply continuity, mentor teams, and apply data-driven automation in a collaborative manufacturing environment.

I am a procurement leader with over 10 years of experience building and running purchasing operations in fast-paced, international manufacturing environments.

I specialize in shaping and executing end-to-end procurement processes — controls, reporting, governance — while delivering measurable savings, compliance, and supply continuity. I led contingency planning during a 2024 disruption that avoided a €1.2M loss and co-created a purchasing policy that cut potential extra costs by 75%.

Hands-on and data-driven, I use advanced Excel (Power Query, PivotTables, formulas), SAP MM, reporting automation, and daily AI tools (ChatGPT, Microsoft Copilot) to streamline analysis and decision-making. I improved OTIF from 70% to 95%, reduced expedited shipping costs by 23%, and supported master data and EDI processes.

I partner across Finance, Planning, Production, Logistics, Quality and customers; mentor junior buyers; lead supplier onboarding and development; and focus on risk-aware continuous improvement and procurement governance.
