Other experience

3d printing Operated and maintained 3D printers to produce accurate prototypes and functional parts from CAD models. Prepared files, optimized print settings, and ensured proper material selection for strength and performance. Performed post‑processing tasks such as support removal, sanding, and finishing to deliver clean, precise components suitable for testing, fit checks, or final use.
Machining Performed precision machining using manual and CNC equipment to produce metal components to specification. Interpreted drawings and measurements to set up, cut, mill, drill, and finish parts with tight tolerances. Ensured accurate dimensions, smooth operation, and consistent quality across all fabricated components while supporting prototype development and production work.
Welding and Metal Fabrication Performed welding and metal fabrication on steel, stainless steel, and aluminum components using MIG and TIG processes. Worked from drawings, measurements, and physical parts to create accurate weldments, repair damaged components, and support prototype builds. Ensured strong, clean welds with proper fit-up, alignment, and finish quality while maintaining consistent workmanship across all projects.
Product Development Engineer As a Product Development Engineer at Crowbar MFG, I specialize in transforming early‑stage concepts into fully realized, production‑ready designs. My role focuses heavily on CAD engineering, where I develop precise 3D models, mechanical assemblies, and fabrication‑ready drawings used for prototyping, testing, and manufacturing.
I work directly from client ideas, sketches, and requirements to engineer solutions that are manufacturable, efficient, and aligned with real-world production constraints. My process blends creative problem‑solving with practical engineering considerations, ensuring every design is reliable, cost‑effective, and optimized for CNC machining, fabrication, or additive manufacturing.
Product Design Experienced product designer specializing in concept development, CAD modeling, and design for manufacturing, delivering practical, market-ready solutions from idea to production.
