As a Senior Mechanical Design Engineer, I specialize in bridging the gap between product concept and mass production. I partner with hardware startups, inventors, and manufacturing facilities to create highly optimized, factory-ready CAD models. My primary focus is on strict Design for Manufacturing (DFM) principles, ensuring that every 3D model can be machined or molded efficiently without expensive factory rejections. Key responsibilities and achievements include: • Designed and engineered 3D industrial mechanical prototypes, delivering accurate STEP files and detailed 2D manufacturing drawings for CNC machine shops. • Specialized in plastic injection molding CAD design, calculating perfect draft angles, uniform wall thicknesses, and rib structures to prevent sink marks or warping. • Conducted comprehensive DFM analysis and CAD design reviews for existing client files, optimizing their geometry to reduce tooling costs and cycle times. • Consistently delivered 100% manufacturing-ready CAD files, successfully pushing dozens of plastic and metal products into mass production. My goal is to protect your manufacturing investment through flawless engineering.
