What I'm looking for

I’m looking for a supply chain role where I can lead global sourcing and planning, improve forecasts and inventory accuracy, and drive cost, delivery performance, and supplier resilience through data-driven, cross-functional execution.

I’m a supply chain and procurement professional with over 5 years of experience driving supplier development, procurement process optimization, and cost control. I bring strong data analysis and supply chain operations experience to coordinate cross-functional teams and execute projects effectively.

In my most recent role as a Supply Chain Planning Specialist, I collaborated with assembly factories and overseas demand teams on capacity planning and demand forecasting. I proactively identified supply risks, improved supply stability, and helped ensure on-time shipment fulfillment through careful coordination of suppliers, factories, and logistics resources.

Previously, as a Global Sourcing Specialist and Procurement Expert, I led global sourcing initiatives and managed end-to-end procurement—from replenishment planning and supplier lifecycle management to payment processing, goods acceptance, and post-purchase reconciliation. I focus on building resilient supply bases, improving inventory accuracy and logistics efficiency, and continuously optimizing procurement cost, lead time, and supply quality.
