Professional Experience

Jeff Lee – Founder of Senquality Statistical Quality Consulting Co., Ltd.
ASQ Certified Quality Engineer | IATF 16949 & VDA 6.3 Auditor

I am a quality engineer with over 10 years of experience across electronics, automotive, and medical device industries. I’ve worked in several multinational companies, including Molex, Corning, and Teradyne, where I led supplier quality management, NPI support, and the implementation of SPC, MSA, and FMEA in both local and global teams.

I founded Senquality to help companies apply quality tools in a practical and effective way—not just to pass audits. My training is hands-on, clear, and focused on solving real problems at the shop floor level.

I’ve built multiple Excel VBA simulation tools, such as dice-based SPC models and interactive GRR practice kits. I also use Canva AI to create high-quality teaching visuals, making statistical concepts easier to understand and apply.

In one project, I helped a flexible circuit manufacturer reduce defects by 35% within 3 months using Excel-based SPC. I believe good quality tools should be simple, explainable, and bring measurable results.

If you're looking for a trainer with real-world experience, cross-cultural background, and a passion for making statistics useful, I’d be happy to work with your team.
