I've spent most of my career working where engineering meets manufacturing. That is where small design decisions become tooling changes, assembly problems, prototype delays, or unnecessary production costs. My role is to identify those issues early, before they become expensive to fix. With more than 12 years of hands-on experience in product development, tooling engineering, precision manufacturing, CNC machining, injection molding, metal stamping, and die casting, I help turn concepts into products that can actually be manufactured, assembled, inspected, and released with confidence. I regularly support projects involving: • Mechanical products and precision assemblies • Plastic injection-molded parts and enclosures • CNC-machined components • Sheet metal and stamped parts • Die-cast components • Manufacturing tooling and production fixtures Typical areas where I can help include: • Mechanical design review and DFM • Manufacturing feasibility assessment • Tolerance stack-up analysis • GD&T and production drawings • Assembly architecture and fastener selection • Prototype optimization for CNC machining or tooling • Injection molding design review (draft, wall thickness, ribs, undercuts, gate feasibility) • Production-ready BOM preparation • Cost reduction and production readiness Before changing a CAD model, I first look at how every part will actually be manufactured, assembled, inspected, and maintained. In many cases, a small design change made early can prevent tooling modifications, machining difficulties, assembly issues, or repeated engineering changes later. Having worked in both engineering and factory environments, I understand the practical trade-offs between design intent, manufacturing capability, quality, lead time, and cost. My goal is not simply to deliver a complete CAD model, but to provide a design that suppliers can manufacture consistently and production teams can build with confidence. If you're looking for someone who understands both product design and manufacturing—and can help move a product from concept to prototype and into production—I'd be glad to help.
