About me
Are you a hardware startup or inventor ready to manufacture your product? I am a Senior Mechanical Design Engineer, specializing in Consumer Electronics and Design for Manufacturing (DFM). I bridge the gap between a bare circuit board and mass production. Whether you need a sleek snap-fit plastic enclosure engineered for injection molding, tight-tolerance SolidWorks CAD for CNC machining, or strict 2D technical blueprints for your USPTO patent application, I deliver flawless engineering. I do not design pretty pictures; I engineer products that actually get built.... Read more
