Worked on Azure/azure-sdk-for-net and Azure/azure-cli-extensions, focusing on backend development and API integration using Python and C#. Delivered a DNS CNAME property backing fix and refactored DNS record class property names in the Azure Provisioning SDK, improving reliability and consistency for DNS provisioning. Enhanced test coverage and updated tests to prevent regressions. In Azure CLI Extensions, implemented input validation for container image names to mitigate shell injection risks and refactored command invocations for better reliability and maintainability. Updated API versions in test recordings, aligning with the latest Azure API and supporting smoother CI workflows through improved test alignment.
