Worked on the broadinstitute/sam repository to enhance data governance and resource management within the Terra Data Repository ecosystem. Developed datasnapshot management as a child resource of datasets, implementing role-based access control and inheritance so dataset custodians automatically become stewards of associated datasnapshots. Leveraged HCL and HOCON for backend configuration management, defining new roles and permissions to support secure, auditable snapshot workflows. Additionally, introduced a new resource type to standardize provisioning and governance of Google projects in TDR, integrating governed actions and IAM roles. These features improved deployment consistency, traceability, and security across data lifecycle and infrastructure management processes.
