Summary

Comprehensive Product Design
I manage the full product development cycle—from market research and concept design to prototyping and mass production. I make sure our products are not only manufacturable but also meet real market needs.

Factory Coordination & Production Tracking
I work closely with factories to keep production on schedule and running smoothly. When issues come up, I act fast to solve them and make sure quality and delivery timelines are on track.

Effective Cross-Department Communication
I’m good at bridging gaps between teams, making sure everyone’s on the same page. This helps projects run more efficiently and increases the chances of success.

Strong Problem-Solving Skills
I stay calm under pressure and can quickly figure out what’s going wrong. I focus on finding practical, workable solutions—fast.
