I specialize in turning product ideas, sketches, existing designs, and real-world problems into functional CAD and physical prototypes. My approach combines digital design with hands-on fabrication. I design parts around how they actually need to fit, assemble, print, and function — not just how they look on screen. I work in Fusion 360 and regularly take designs directly from CAD into FDM prototypes for fitment testing, assembly, and iterative revision.
