Background
Background and Professional Focus
I am an FE mechanical engineer, Certified SOLIDWORKS Expert, and CU Boulder graduate with a minor in Engineering Entrepreneurship. My path runs through aerospace concepts, production hardware, teaching, racing drones, and a long list of self-assigned design problems.
Across these roles, I focus on understanding constraints, documenting decisions, and improving each design through testing. I apply the same approach to products, teams, and technical education.
