PROJECTS

SENIOR DESIGN:
FALL PROTECTION

2024 – 2025

Collaborated within a five-person engineering team to develop three distinct fall protection prototypes for Samsung Austin Semiconductor. Modeled and simulated structural designs in Autodesk Inventor to meet a rigorous 3,600-pound load specification. Utilized manual milling, lathe operations, and welding to fabricate and physically test multiple iterations, translating complex digital models into functional hardware and analyzing real-world load limits.
