PROFILE
Jj Kavelaars
In October 2025, JJ Kavelaars developed a security-focused authentication integration for remote Butler services in the lsst/daf_butler repository. He implemented a CADC authentication provider that mirrors the Rubin pattern, using Python to handle bearer tokens via environment variable lookup and enforce domain whitelisting for CADC access. This approach enhanced secure, authorized connections while reducing token exposure and aligning with established authentication standards. JJ also updated the test suite to reference the new CADC module, improving coverage for the authentication path. His work demonstrated depth in API integration, backend development, and testing, resulting in a robust, maintainable authentication solution.
