About
I am a Mechanical Product Development Engineer with 20 years of experience in mechanical design, tooling, and manufacturing.
My work focuses on developing mechanical products that are practical to manufacture, assemble, and produce reliably at scale.
I work across the full mechanical development process, from concept evaluation and mechanism design to detailed CAD, DFM, and production documentation.
My areas of expertise include:
• Mechanical Product Development: Product architecture, mechanism design, mechanical assemblies, and prototype development.
• Design for Manufacturing (DFM): Design optimization for injection molding, plastic extrusion, CNC machining, and sheet metal fabrication.
• Tooling & Mold Design: Injection mold design, plastic extrusion tooling, stamping dies, and deep drawing processes.
• Mechanical Engineering: Load calculations, motion and kinematic analysis, material selection, and tolerance stack-up analysis.
• Production Engineering: SolidWorks 3D modeling, 2D engineering drawings, GD&T, BOM, and manufacturing documentation.
I also have experience using Moldflow, Dynaform, and DEFORM 3D to evaluate manufacturing processes and identify potential production issues.
I have worked with manufacturers and suppliers in Vietnam, China, and Taiwan, giving me practical insight into tooling constraints, manufacturing processes, and production requirements.
My approach is straightforward: identify engineering and manufacturing risks early, select practical solutions, and develop designs that can move from prototype to production without unnecessary complexity.
I can support individual engineering tasks or take responsibility for a complete mechanical design package, depending on the project requirements.
