Chinese name

Ethan Fang

Based out of the Bay Area. I spend most of my time in math modeling, AI research, and engineering.

I graduated in 4 years from Case Western Reserve University in May 2026 with a dual BS/MS degree in computer science. During my time there, I cofounded the quant finance club, grew the tennis club to record participation, and did lots of research.

Currently, I am a Software Engineer at Fluency, where we are building a work ontology to automate processes in enterprise companies. Previously, I was a quantitative analyst at KeyBank for 1.5 years, where I worked on statistically-backed sequential feature selection, distributed computing, and backtesting for the modeling codebase used by the quants at the bank.

I am passionate about researching and building technologies that create meaningful real-world impact. My interests include sustainability, human-centered AI, and athletic performance. In my free time, I read about game theory, do research on differential equations, and teach tennis to competitive juniors in my hometown.

Previously

I was a nationally ranked junior tennis player, and a California All-State violinist for 6 consecutive years.
