Summary
Detail-oriented CNC Machinist and Programmer with 14+ years of experience in medical, aerospace, military and defense manufacturing environments operating under ISO 9001:2015 standards. Proven expertise in holding tight tolerances, advanced blueprint reading, and extensive GD&T application to produce precision, high-quality components. Skilled in full machine setups, multi-axis CNC machining (Swiss and mills), tooling optimization, and G-code programming and troubleshooting. After several years in independent technical contracting, I am seeking to return to CNC machining where I can apply my strong quality focus, precision workmanship, and deep manufacturing experience to contribute immediately in a high-performance production environment.
