Top SchoolDaniel Watkins is a Senior Software Engineer with 17 years of experience building and hardening backend systems, currently contributing to supply-chain and cloud-native security at Chainguard. A long-time free-software advocate and consultant, he has deep roots in the open-source community with substantial contributions to projects like RustPython, mypy, cloud-init and the popular neovim testing framework neotest. He excels at pragmatic refactors, type-system improvements, interpreter back-end fixes, and test tooling—work that often focuses on maintainability, developer experience, and correctness rather than flashy features. Based in Kingston, Ontario, he blends hands-on engineering with leadership experience from roles at Canonical and DigitalOcean, and brings a track record of shipping careful, community-oriented solutions across language ecosystems. An understated strength is his ability to bridge low-level interpreter and type-checker details with higher-level system integration, improving tooling that benefits large developer communities.
