I help startups and engineering teams develop electromechanical products—from concept and CAD through prototyping, testing, and manufacturing support. Prosthetics and robotics are specialties, not the limit of what I build.
A look at my work.
A non-backdrivable brake mechanism allows the prosthesis to switch between active and passive modes—providing assistance during activities like stairs and sit-to-stand while allowing passive operation during walking phases where energy input is unnecessary or battery power is limited.
Originally designed to test two AFO's. Independent cycle frequency adjustment on each side.
Physical build of the patented biomechanical motion device (WO2022086498A1) for replicating human gait loads.

A production foot Fillauer sells today — the platform I'm now building the next generation of, with added functionality.

We use modified ski boots to test the feet we are developing.

Comfortable programming and running CNC machines to produce precision parts.

Replaced the head gaskets, checked valve clearances, and installed new injectors to get this K100 motorcycle running again. Electrical work to come. I like keeping this type of hands-on work in the mix.
Built a 15-foot skiff from scratch - ash frame, plywood panels, fiberglassed seams.
A working history across design, testing, and product development — from graduate student research through commercial, production-ready hardware.
R&D experience from concept through verified, field-tested hardware.
Formal training in mechanical engineering, plus co-invented IP filed alongside research and industry teams.
