If youโre looking for more than just a 3D concept โ if you need real, functional product designs built for manufacturing, prototyping, and actual use โ I can help. Iโm a U.S.-based mechanical/product engineer with over 15 years of CAD design experience and a proven track record of bringing physical products to life. My designs arenโt just for show โ theyโve been manufactured, tested, shipped, and used by real customers in real environments. From precision mechanical assemblies to injection-molded components, 3D-printed prototypes, and production tooling, Iโve delivered complete solutions for clients ranging from startups to major manufacturers. Iโve worked as a Senior Product Engineer at a publicly traded company, contributed to government and defense programs, and designed parts for industries including 3D printing, firearms, consumer electronics, and industrial automation. What sets me apart: Manufacturing-ready CAD โ not just pretty renders Experience with real-world constraints โ tolerances, cost, DFM, ergonomics, stress, material choice Hands-on engineering insight โ I donโt just model, I solve problems Clear U.S.-based communication & accountability โ timelines, documentation, and results you can count on Yes, my rates are higher than offshore freelancers โ but you're paying for proven reliability, quality you can manufacture, and a designer who understands the why behind every decision. Whether you need to make a new idea, optimize a prototype for injection molding, or take your napkin sketch to production โ Iโm ready to help. Letโs build something real.
