ResumeAbout

/ About me

Curious by default.
Rigorous by practice.

I’m completing my aerospace engineering degree at the University of Colorado Boulder. My experience includes a systems engineering internship at Sierra Space and a test engineering internship at Kairos Power.

Different domains, same motivation: understand the system, ask the useful question, and build evidence strong enough to move forward.
