Hey there!

I’m Noah Lev. I’m one of the developers of the Rust programming language, as a member of the Compiler and Rustdoc teams. I also develop systems research projects in Prof. Emery Berger’s PLASMA lab at UMass Amherst. At UMass, I’m studying for my bachelor’s degree in Computer Science.

How I made Rustdoc 25% faster in one week

From a “weird bug” to massive speedups

Outside of computer science, I’m a photographer, focusing on the arts, cities, and wildlife. I work for the UMass Fine Arts Center, and I’ve had the opportunity to photograph many amazing artists, including the Paul Taylor Dance Company, Venice Baroque Orchestra, and many more. See some of my photos below!
