Frossie developed and enhanced deployment and data management systems for the lsst-sqre/phalanx and lsst/tutorial-notebooks repositories, focusing on secure access control, reliable file storage, and robust tutorial delivery. She implemented Argo CD role-based onboarding and governance to streamline developer collaboration while maintaining security. Using Python, YAML, and DevOps practices, Frossie stabilized tutorial deployments by aligning configuration and filesystem paths, and improved code maintainability through targeted cleanup and refactoring. Her work culminated in production-ready WebDAV file server enablement for persistent user data storage, demonstrating depth in configuration management, file system operations, and change tracking across complex, multi-repository environments.
