CNC Programmer | CAD/CAM Specialist

Xometry Europe • Freelance

Nov 2023 - Present • 2 yrs 11 mos

Lead advanced CAM programming and production preparation workflows for the Xometry Europe supplier network, specializing in high-efficiency CNC milling and multi-axis turning applications. I convert complex customer 3D models and engineering drawings into precise, production-ready manufacturing strategies using Mastercam and Autodesk Fusion 360. My responsibilities include developing highly optimized 3-axis, 4-axis, and simultaneous 5-axis toolpaths, defining critical tool selections, and structuring aggressive high-speed machining (HSM) cutting parameters. I perform rigorous virtual toolpath simulations to guarantee 100% collision-free execution, ensure flawless surface finishes, and minimize cycle times to maximize shop floor throughput. I actively review part geometry for Design for Manufacturability (DFM), resolve complex geometric constraints, and engineer post-processed G-code customized for distinct machine controllers. Additionally, I generate comprehensive manufacturing documentation, detailing work coordinate systems (WCS/G54) and structured tool lists to guarantee absolute execution accuracy on the first run. Core Competencies: • Mastercam & Autodesk Fusion 360 CAM Engineering • 3-Axis, 4-Axis, and Simultaneous 5-Axis Programming • CNC Milling Center & High-Precision Lathe Turning • Error-Free G-Code & NC File Generation (Haas, Fanuc, Mazak) • Advanced Toolpath Simulation & Collision Avoidance • Geometric Dimensioning & Tolerancing (GD&T) Mapping

Lead CAD/CAM Engineer & Manufacturing Consultant

Toptal • Freelance

Jun 2022 - Present • 4 yrs 4 mos

Function as an elite, vetted CAD/CAM Consultant within Toptal’s exclusive engineering network, delivering remote, high-ticket manufacturing programming for complex industrial and aerospace clients across the United States and Europe. I serve as a dedicated technical partner for companies needing emergency CAM interventions, multi-axis deployment, and process optimization. My responsibilities focus on programming tight-tolerance structural parts, high-precision molds, and medical components using Mastercam and Fusion 360. I step in to resolve complex toolpath bottlenecks, program simultaneous 4-axis and 5-axis operations, and configure live-tooling CNC lathes. Every delivery undergoes rigorous machine dynamic verification to protect client machinery from costly collisions or scrap production. By analyzing raw 3D models and engineering layouts, I provide actionable Design for Manufacturability (DFM) feedback that slashes machining cycle times and preserves tool life. I deliver optimized, post-processed G-code engineered to drop directly into Fanuc, Haas, Mazak, and Heidenhain industrial controllers for immediate, first-pass production success. Core Accomplishments: • Successfully programmed and optimized complex components for aerospace and medical equipment. • Consistently reduced client production cycles by implementing advanced high-speed machining (HSM) toolpaths. • Vetted into the top tier of international remote engineering talent for technical manufacturing execution.
