I have worked in machine shops since high school doing production process development. Programming CNC machines is my thing. I've worked in many different environments from production, prototype, job shops and startup machine shops. Learning machining before learning design and engineering has taught me to design things that are practical for manufacturing, and catch issues on parts before they go into production. This allows me to analyze designs and offer suggestions that will make producing your product cheaper.
