Nicole Wren is a software engineer with eight years of experience building backend systems and tooling, currently at Block in Pasadena. Her background spans systems and languages—from Haskell networking automation and frontends to Rust high-performance runtime research—demonstrating fluency with both low-level concurrency and practical product work. She contributed to the Unison language upstream, improving its printer and lexer to handle complex formatting and multiline constructs, showing attention to language tooling and developer ergonomics. As an undergraduate researcher and long-time CS teaching assistant at Georgia Tech, she pairs rigorous benchmarking and documentation skills with a knack for teaching and automation. That blend of production engineering, programming-language contributions, and HPC benchmarking gives her a rare cross-cutting perspective on correctness, performance, and usability.
