Worked on enhancing Azure REST API specifications by introducing support for the RollingBack state in upgrade rollback scenarios. Focused on aligning the 2026-03-01 ComputeRP swagger with actual CRP behavior, this developer added new enum values to both UpgradeState and RollingUpgradeStatusCode, addressing deserialization issues in the Track 2 .NET SDK during rollback operations. The work involved regenerating swagger definitions after merging with the main branch to ensure downstream client compatibility and prevent runtime errors. Collaborated across teams within the Azure/azure-rest-api-specs repository, leveraging skills in API development, Swagger, and TypeSpec, with a strong emphasis on JSON schema accuracy.
