Worked on cross-repository delivery of a new API version for Azure Communication Rooms, focusing on role-based access improvements and safer collaboration. Updated the welovej/azure-rest-api-specs repository to introduce the 2025-03-13 API version, aligning documentation and specifications while addressing type validation. Enhanced both the Python and .NET SDKs by adding a Collaborator role, updating models, changelogs, and tests to support improved participant management. Emphasized consistency across REST, Python, and .NET implementations, ensuring traceable releases and robust version control. Utilized skills in API specification, SDK development, and Python to accelerate customer adoption and strengthen cross-language alignment for Azure Communication Services.
