About

Certified Industrial Engineer (CIE) currently working as a Process Engineer in the semiconductor manufacturing industry, with hands-on experience in ceramic substrate processes, CNC fiber laser drilling, and continuous improvement. In my current role, I focus on troubleshooting and root cause analysis (RCA) to resolve production issues, reduce defects, and improve overall yield. I am actively involved in implementing process improvements and generating monthly reports to track performance and identify optimization opportunities. I also handle CNC fiber laser drill programming for new product development, ensuring precision, consistency, and manufacturability. My work involves close collaboration with production, quality, and engineering teams to support stable operations and continuous improvement initiatives. Lean Six Sigma (White & Yellow Belt) certified, with a strong foundation in data-driven problem solving and process optimization. I am continuously looking to grow as a Process Engineer and contribute to high-impact engineering solutions in manufacturing and operations.
