Worked on the Azure/azure-rest-api-specs repository to stabilize SecurityInsights API versioning and unify OpenAPI delivery across both stable and preview releases. Leveraged TypeSpec and OpenAPI to implement versioning decorators for preview resources, consolidating schema generation into a single openapi.json and updating linting to target bundled files. Enhanced documentation quality by adding comprehensive OpenAPI examples and ensuring API-version accuracy, while refining model naming and required field handling to align with lint rules. Coordinated packaging and repository hygiene improvements, introducing new tags and contributor guidance. These efforts reduced breaking-change regressions and improved the developer experience for REST API consumers.
