About

I am a Mechanical Product Design Engineer with experience in developing consumer electronic products from concept to mass production.

My expertise includes plastic enclosure design, bracket and sheet metal design, waterproof (IP) structure review, DFM (Design for Manufacturing), tolerance analysis, and production support.

I have extensive experience collaborating with overseas suppliers, reviewing prototypes, identifying mechanical issues, and implementing design improvements for manufacturing.

My services include:
• 3D CAD Modeling (SolidWorks)
• 2D Manufacturing Drawings
• Plastic Part Design
• Bracket & Sheet Metal Design
• DFM Review
• Injection Mold Design Support
• Assembly Design
• Mechanical Design Validation
• Engineering Change (ECO)
• Prototype Review
• Mass Production Support

I focus on practical, manufacturable designs that reduce production risk while improving product quality.
