Your factory speaks Chinese. Your drawings speak English. I speak both.
I turn ideas into production-ready CAD drawings — and help you communicate them to China factories without misunderstandings, delays, or costly mistakes.
With 10 years of experience in kitchen and millwork design, I provide precision shop drawings that are not just accurate, but truly buildable. My files are clean, layered correctly, and ready for the shop floor — whether it's in Charleston or Guangdong.

I'm a Certified SOLIDWORKS Expert (CSWE) and Mechanical Design Engineer with 16+ years of hands-on manufacturing experience. I specialize in SolidWorks, sheet metal, DFM, production-ready CAD, and mechanical product development.
I help clients turn concepts, sketches, existing parts, drawings, or measurements into practical, manufacturable designs.
My core services include:
• Mechanical part and assembly design
• Sheet metal enclosures, cabinets, brackets and fabricated assemblies
• Design for Manufacturing (DFM) and Design for Assembly (DFA)
• Production drawings, GD&T, tolerances and BOMs
• Flat patterns, bend allowances, DXF/DWG and fabrication files
• Reverse engineering from physical parts, measurements, photos and 3D scan data
• 2D/PDF drawings → 3D CAD
• 3D CAD → manufacturing drawings
• Product development and prototyping
• 3D-printing product design
My engineering experience extends beyond CAD.
I have practical experience with sheet metal fabrication, laser cutting, CNC punching, bending, welding, machining, prototyping and production.
I have also worked with manufacturing and CAD/CAM tools including:
• SOLIDWORKS / SOLIDWORKS Sheet Metal
• AMADA SheetWorks
• AMADA VPSS3i / VPSS3iE
• CNCKAD
• CypCut
• AutoCAD
• Autodesk Inventor
• Mastercam / SolidCAM
This manufacturing background helps me design parts that are not only accurate in CAD, but realistic and efficient to manufacture.
I also have hands-on product development and 3D-printing experience.
For one client, I developed 62 different 3D-printed products, taking designs from concept and CAD development through prototyping and design revisions.
I operate a Bambu Lab P1S 3D printer in my workshop, giving me practical experience evaluating designs as physical prototypes rather than only as digital models.
I also work on reverse-engineering projects where the original CAD is unavailable.
I can work from 3D scan data, physical components, hand measurements, reference photographs, existing drawings, and legacy or damaged parts.
My goal is to reconstruct functional, production-ready CAD rather than simply reproduce the visible geometry.
If your project needs more than a CAD model — especially if the final design needs to be laser cut, punched, bent, welded, machined, assembled or prototyped — my combination of mechanical design and manufacturing experience can help take it from concept to production.
Send me your drawings, sketches, photos, measurements, existing CAD files, or project requirements, and I can help determine the appropriate design and manufacturing approach.
