As a Senior Mechanical CAD Engineer, I partner with hardware startups, inventors, and manufacturing facilities globally to bridge the gap between product concept and mass production. My primary focus is strict Design for Manufacturing (DFM) principles. I ensure that every 3D model can be machined or molded efficiently without expensive factory rejections. Key responsibilities and achievements include: • Engineered 3D industrial mechanical prototypes, delivering accurate STEP files and detailed 2D manufacturing drawings with exact tolerances 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 in plastic products. • 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, German-standard engineering.
