Zanie Blue is a software engineer with a decade of experience building high-performance developer tools and robust build automation, currently contributing to Astral’s unified Python toolchain. She has led backend work at Prefect—shaping its open source orchestration product—and contributed to major projects like CPython, Prefect, and the fast Rust-based linters and package managers at Astral. Her strengths span backend systems, CI/CD and release engineering, and testing infrastructure, with notable work improving BOLT integration and cross-compilation in CPython. She’s also focused on developer experience and reliability, adding resiliency and retry logic to package downloads and hardening linter behavior and memory use. A lifelong open-source practitioner, she prefers working in the open and iterating directly in public repos. Outside engineering, her background in neuroscience and hands-on leadership (including directing a large sailing program) give her a data-driven yet practical approach to problem solving.
