About

Headshot

I'm a junior in mechanical engineering at UC Berkeley (GPA 3.92). I transferred from Diablo Valley College, where I earned an A.S. in Mechanical Engineering with a 4.0.

On AeroSAE I'm on the landing gear team, where I size structures with hand calcs and FEA and then check them against physical tests. Outside the team I build mechanisms and small electromechanical systems: gear trains, grippers, and sensors I can test in the real world.

I'm looking for a summer 2027 internship in aerospace or mechanical design.
