Worked on expanding the API surface for Azure’s azure-rest-api-specs repository by delivering the Discovery Control Plane Public Preview for Bookshelves. Developed new resource models and operations to enable Bookshelves creation, configuration, and management of private endpoint connections and link resources. Coordinated the public preview release, ensuring alignment with API specs governance and preparing documentation for downstream consumers. Utilized TypeSpec for API definition and leveraged skills in API development, Azure SDK development, and cloud services to implement the feature. Focused on release readiness and compatibility, with no major defects reported, setting the stage for broader adoption and future API stabilization.
