1.Took charge of technical management.2.Played a dominant role in production and operation management, including on-site maintenance, employee performance inspection, supervision over defect-free rate, and OEE. 3.Enhanced production efficiency by implementing overall planning upon maintenance and upgrading, as well as automation in the manufacturing process.4.Monitored the budget controlAchievements: 1.Lowered defective rate of Apple I6 Housing from 5.13% to 2.37% by making modification to product contour polishing and using automated compensation systems 2. Modified clamping devices, cutting angles, and machining parameters, to lower the defective rate to 5.64% for the products of Apple iPad Mini V8 Base 3.Improved first pass yield of Bose Over-Ear Phone housing from original 51.12% to 75.23% after solving the problems of defects like the white powdery substance on the product surface 4.Introduced TPM and combined with ERP system, the first level, and secondary maintenance plan, to ensure that the average operation rate is above 81.31%, and the TEEP is maintained in the range of 65%.5.Introduced automatic clamping system into CNC workshop, which effectively reduces the clamping and loading time by 8.17%;Other: 1.In 2013, I was assigned to Zeniya Aluminum Engineering Co., Ltd.(Qianwu Corporation), the largest supplier of mobile phones and 3C appearance parts, to study high-speed milling, process splitting, fixture tooling design, and other process technology points by Apple's strategic planning. During these 4 months, I learned high-speed milling technology and other process points;2. I was selected as the outstanding employee of the group in 2014; 3. I passed the PMP certification in 20164. I obtained Lean Production certification of PEGA group in 2016
