Ethan Xu
Hey, I'm Ethan. I study CS at Berkeley as a Regents' and Chancellor's Scholar. When something sparks my interest I get hyperfixated. I haven't run out of things to be curious about yet.

I build machine learning models and the data pipelines behind them. Right now I'm interning at Coupang, turning product images and seller data into structured listings with computer vision and LLMs, and at Climformatics, forecasting solar weather two weeks out. Before that: trading-strategy backtests, sentiment models that read earnings calls, and a NeurIPS workshop paper on sentiment drift in LLMs. I've also spent four years teaching kids around the world to code.
