Worked on enhancing data publishing and storage reliability across Azure/azure-cli-extensions and Azure/azure-storage-fuse. Developed a new subdirectory parameter for dataset publishing in the CLI extension, ensuring compatibility with various encryption modes and updating both the API and SDK templates. Added comprehensive unit tests and documentation to support these changes, using Go and Python for backend and CLI development. Addressed a critical bug in Azure Storage Fuse by correcting path resolution for CPK-encrypted block blobs within subdirectories, preventing misrouting and ensuring accurate file access. The work demonstrated a focus on robust validation, cloud storage integration, and maintainable code quality.
