At Jassen Harris Industries, I owned the mechanical design for a universal testing machine concept, including structural FEA, component specifications, and its BOM. I also designed mechanisms for a 100-unit kinetic wall installation.

As an independent freelance CAD designer and fabricator, I designed SolidWorks parts, mechanisms, and assemblies, then built and iterated functional 3D-printed components. I also designed and assembled the VZBot large-format 3D printer; its high-temperature operation validation remains in progress.
