PROFILE

Richard Hallett

Worked on the datacite/lupo repository to enhance metadata lifecycle management and streamline repository import workflows. Introduced a destroy hook for S3-stored metadata, enabling controlled deletion of obsolete objects and supporting data retention compliance while reducing storage costs. Improved the repository import process by disabling DataCatalog fetches when the re3data API is unavailable, ensuring uninterrupted reindexing. Removed page-limit logic to allow full imports and performed RuboCop-driven code quality improvements in Rake tasks. Leveraged Ruby, Ruby on Rails, and AWS S3 throughout, with a focus on backend development, static analysis, and maintainability to strengthen data governance and operational resilience.
