Rockstar🎓
Top SchoolKellie Medlin is a Senior Software Engineer based in the San Francisco Bay Area with a decade of experience spanning FAANG and startup environments. She specializes in developer tooling, build systems, and compiler-adjacent work—contributing to high-profile open-source projects like Buck and xcbuild to improve cross-platform builds and toolchain compatibility. Comfortable in Rust, C++, Python, and build systems like Buck and CMake, she focuses on removing long-lived technical debt and hardening internal deployment pipelines. Kellie pairs a security-minded, systems-level perspective with a pragmatic, get-it-done startup attitude and a personal preference for functional, strongly typed languages. Outside of code she connects communities through coffee, an unexpected conduit that’s broadened her network and sharpened her collaborative instincts. Her background from Carnegie Mellon and deep tooling experience make her a go-to engineer for complex build and platform challenges.
