What I'm looking for

I'm open to relocation and international opportunities.

At United Grinding China, I led an eight-month Six Sigma Black Belt project that turned passive KPI reporting into an actionable performance-management system. Using DMAIC, process mapping and root-cause analysis, I achieved full KPI actionability and improved organisational efficiency by 20%.

As an independent consultant, I work across sourcing and operational improvement, coordinating suppliers, logistics and business stakeholders through implementation. Supplier benchmarking and cost analysis helped reduce packaging costs by 40% and other supply costs by approximately 20%; I also build recurring Excel analyses to turn performance trends into practical actions.
