I help companies turn product ideas into manufacturable products ready for production. With over 30 years of product development experience, I specialize in designing products that are not only functional and attractive, but also optimized for manufacturing processes such as injection molding, sheet metal fabrication, blow molding and die casting. Many companies struggle to move from concept to a product that manufacturers can actually produce economically. My work focuses specifically on Design for Manufacturing (DFM) so that your product can move efficiently from prototype to mass production. I regularly assist clients with: • Consumer product development • Electronic enclosure design for PCB devices • Plastic product design for injection molding • Bottle and container design for blow molding • Mechanical product design for sheet metal fabrication • Industrial equipment and vehicle accessories My goal is simple: create product designs that manufacturers can build reliably and cost-effectively. What you can expect when working with me ✔ A professional 3D CAD product design ready for manufacturing ✔ Designs optimized for injection molding and production ✔ Clear communication and progress updates ✔ Collaboration with your manufacturers worldwide Experience • Mechanical Engineering Degree (1994) • 30 years product development experience • Top Rated Plus freelancer on Upwork • ~$300K earned on the platform Previous clients include companies such as Ford, Toyota, BMW and Unilever, as well as startups and inventors developing new patented products. If you are looking for an experienced designer who understands both product development and manufacturing, I would be happy to assist with your next project.
