Worked on strengthening API contracts and enhancing SDK robustness for Azure Purview Data Map integrations. In the welovej/azure-rest-api-specs repository, implemented type enforcement for Datamap API endpoint URLs using TypeSpec, shifting from a generic string to a validated URL type to improve contract validation and runtime handling. In the Azure/azure-sdk-for-python repository, improved the DataMap SDK by refining type annotations, refactoring error handling, and hardening response deserialization, which increased maintainability and runtime resilience. Leveraged Python, TypeScript, and API specification skills to deliver targeted improvements that support developer productivity and ensure more reliable integrations with Azure Purview Data Map services.
