Background

Engineering grounded in real hardware.

I'm a mechanical engineer (B.S., Cal State LA) with five years of experience on the hardware side of robotics and automation: humanoid robot fleet support, battery and thermal validation, and production equipment maintenance.

My work has centered on diagnosing physical systems, isolating mechanical, electrical, and software faults, and supporting the test and repair work needed to return equipment to operation.

3DXera is my independent portfolio and engineering workspace: a home for mechanical design, robotics, controls, simulation, test and validation, and physical engineering projects.
