Cell Line 1. Participated in the initial startup of the cell manufacturing plant, working closely with industrial engineers, project teams, and contractors to align project milestones and ensure smooth progress from construction to operation. 2. Automated SOP translation and editing processes by developing VBA scripts in Excel, significantly reducing manual workload and turnaround time. 3. Coordinated with logistics teams and vendors to track equipment shipments, schedule unloading crews, and prepare tools, while providing daily safety data information to ensure all handling steps followed strict safety protocols. 4. Designed and optimized unloading workflows, generating cost savings of nearly $1M through efficiency improvements. 5. Maximized temporary storage capacity by designing layouts in AutoCAD and simulating 3D stacking with Fusion 360, achieving safer and more efficient space utilization. Pack Line: 1. Collaborated with equipment vendors on installation and commissioning of new machinery, accelerating ramp-up timelines and securing reliable production startup. 2. Reduced average daily downtime to less than 1 hour by implementing proactive maintenance and fast-response troubleshooting, ensuring higher equipment availability and production stability. 3. Improved line capacity by conducting daily OEE analysis to identify bottlenecks and implementing targeted optimizations, including servo motor/cylinder/robot speed adjustments and cycle time reduction through equipment logic improvements. 4. Increased first-pass yield (FPY) by performing regular tooling inspections and redesigns, improving line quality and reducing rework. 5. Trained production staff on equipment operation, reset procedures, and tooling usage, strengthening team capability and minimizing operator-related stoppages.

1. Participating in the initial startup of the TopCon (N-type) PV module manufacturing plant (up to 7GW), working closely with IEs, project departments, and contractors to ensure project progress. 2. Auditing weekly process schedules and promptly addressing any issues by providing feedback and proposing solutions. 3. Analyzing equipment department needs for the early stages of factory startup, and generating purchase requisitions for required tooling and fixtures. 4. Guiding on-site planning and equipment unloading and placement for contractors. 5. Guiding on-site secondary distribution system installation. 6. Reviewing the accuracy of current 2D drawings, ensuring alignment with specifications. 7. Conducting training sessions for new team members, covering photovoltaic industry processes, quality requirements, MES and CMMS systems, equipment maintenance procedures, and solar panel manufacturing processes. 8. Providing weekly progress reports to headquarters on the advancement of the manufacturing plant project.

1. Led a team of 15 people to maintain the plant equipment and machine modifications, resulting in a 20% increase in production capacity under my leadership. 2. Write project proposals to show the benefit of new improvements, risk analysis, and ROI. After project start, regularly track the progress of the project (Gantt chart) and resolve any difficulties that will be encountered. 3. Work with Process Team and Quality Team to quickly identify where the problems are located and solved the problems as soon as possible. Summarize and write a Formal work package (FWP) for the team to reduce machine downtime and safeguard the safety of employees. 4. Evaluate the usage or life cycle of machine parts to achieve reasonable inventory control. 5. Analyze the inventory data every week and list all consumable parts that need to be purchased to ensure that all machines have enough spare parts for maintenance and operation. 6. Analyze the structure of machine parts and the principle of operation, redesign and prototype the failed design or parts. The Main CAD softwares are Autodesk Inventor, Autodesk Fusion 360, and SolidWorks. Main CNC machine is Tormach 1100MX CNC Mill. The main 3D printers are Formlab 3L, Anycubic Photon, and Ender. 7. Analyze and plan the next year's annual budget for the equipment department to obtain a sufficient annual budget. 8. Reduce significant operating costs for the company by developing and manufacturing parts in-house

My main job was providing technical support to students and doing marketing for the student leader department. During my work-study at Valencia College, I had three job training over a year. During the training, I learned how to communicate with co-workers and customers, and I build up teamworking skills during this position. I also learn how to network out of school and improve communication skills.
