I design and prototype functional mechanical parts and assemblies using Onshape — from precision-fit components to complex, motion-driven systems — and 3D-print working prototypes to validate designs quickly.
My background is 3 years as lead/core designer for my FIRST Tech Challenge (FTC) robotics team, where I was responsible for the mechanical design of our competition robot: motor-driven drivetrains, chain and sprocket power transmission, shaft and bearing assemblies, and structural chassis design, all built to survive real competitive use, not just look good on screen. That experience taught me to design for actual function under real constraints — fit, tolerance, durability, and assembly — not just visual concepts.
Beyond mechanical systems, I also design organic and ergonomic surfaces where parts need to conform to a hand, body, or existing shape, and precision threaded/functional components where multiple parts need to seal, slide, or thread together correctly.
What I can help with:

Converting your sketch, reference photo, or rough idea into an accurate, print-ready CAD model
Functional prototyping — iterative design, print, test, and revise cycles until the part actually works
Precision-fit mechanical assemblies (motors, shafts, bearings, gears, chain/sprocket systems, fasteners)
Ergonomic and organic surface design
Reverse-engineering existing or broken parts into clean, corrected CAD files

I always confirm scope, references, and expectations with you before starting work, and I build in a review checkpoint on any larger project so you're never surprised by the final result.
Software: Onshape (advanced). Comfortable working from STEP, STL, or reference images/dimensions.
