Strategic Sourcing & Cost Control: Spearheaded a major cost-reduction initiative in supply chain management for substrates and MO source vendors, achieving significant bottom-line savings through strategic vendor negotiations. R&D Project Leadership: Managed multiple new pHEMT projects. Operational Excellence: Directed a throughput enhancement project that increased capacity by 5% by identifying and eliminating bottlenecks and modifying production flow to shorten cycle times. Quality & Customer Relations: Served as the primary Customer Complaint Coordinator, collaborating with process integration team to resolve technical issues and maintain high levels of customer satisfaction.

Production Scaling & Efficiency: Spearheaded a continuous improvement project that optimized workflows, resulting in a 10% increase in overall throughput. Cross-team cooperation: coordination of maintenance and process, coordination of process and cusotmer Capacity Expansion: Managed the technical release (ECN) of a new G3 MOCVD reactor, successfully integrating it into the pHEMT mass production line. High-Volume Leadership: Led a team to maintain high-level production output. Facility Migration & Change Management: Directed the complex relocation of a reactor from FAB_B to FAB_C, ensuring minimal downtime and a successful ECN release for continued pHEMT mass production in the new facility.
