Mathematics of Computation @ UCLA

Quantitative finance, machine learning, and full-stack development. Building tools that find signal in noise.

About

I'm a freshman at UCLA studying Mathematics of Computation, blending applied math with computer science. My work sits at the intersection of quantitative finance, machine learning, and software engineering.

I've built ML-driven stock prediction engines, published research on cancer genomics at Yale's Townsend Lab, and co-authored econometric studies at the Fudan-Stanford Institute. On the engineering side, I've shipped a campus iOS app to the App Store, built Chrome extensions that reverse-engineer AI chatbot DOMs, and designed automated market screeners that analyze 4,300+ equities daily.

I care about building things that work—tools that find edge, systems that scale, and research that matters.
