Elijah has always enjoyed working at the intersection of math and engineering. More recently, he has focused his career on building tools to make data scientists more productive. At Two Sigma, he was building infrastructure to help quantitative researchers efficiently turn ideas into production trading models. At Stitch Fix he is a founding member of the Model Lifecycle team â€” a team that focuses on streamlining the experience for data scientists to create and ship machine learning models. In his spare time, he enjoys geeking out about fractals, looking at antique maps, and playing jazz piano.
