Worked on expanding the Azure SDK Model Dataplane within the Azure/azure-rest-api-specs repository, focusing on deployment templates and accelerator configuration support. Developed new fields to enable precise control over allowed deployment templates and accelerator mappings, ensuring compatibility across API versions and related assets. Coordinated cross-repository model alignment, addressing field placement and versioning to reduce breaking changes. Enhanced documentation by adding detailed examples and updating usage guides, supporting future-proof deployment scenarios. Utilized TypeScript and JSON for modeling and SDK development, emphasizing code quality and maintainability. The work delivered a more expressive, consistent API surface for deployment and registry SDK adoption.
