Most CAD models look good on screen but are difficult to build in the shop. I specialize in turning designs into production-ready parts and assemblies that are easy to cut, bend, weld and assemble. Mechanical designer with 20+ years of experience, focused on Design for Manufacturing (DFM) and real-world fabrication. I help transform ideas, sketches, or existing CAD models into practical, buildable solutions — reducing cost, simplifying production, and improving reliability. What I do best: • Sheet metal design (laser cutting, bending, welding) • Fixing and improving CAD models for manufacturing • Creating production-ready files (DXF, STEP, shop drawings) • Reverse engineering from photos, sketches, or measurements • Reducing part count and simplifying assembly • Tolerance stack analysis • GD&T tolerances I also have strong experience in: • Mechanical design of automated machinery and assemblies • Plastic part design for injection molding (DFM, draft angles, ribs, bosses, tooling considerations) My approach is always practical: I design parts based on how they will actually be manufactured, assembled, and used — not just how they look in CAD. ✔ 16,000+ hours on Upwork (Top Rated Plus) ✔ 50+ satisfied clients ✔ Strong focus on real-world, buildable engineering solutions If you need someone who understands both design and how things are actually built, I can help. ✅Keywords Mechanical Design Sheet Metal SolidWorks PTC Creo Design for Manufacturing (DFM) CAD Design Product Design Fabrication Laser Cutting Metal Fabrication Welding Bending Manufacturing Drawings DXF STEP Machine Design Assembly Design Reverse Engineering Injection Molding Plastic Design Mold Design
