Contributed to the azure-rest-api-specs repository by delivering three features over two months, focusing on API robustness, maintainability, and resource management. Enhanced API reliability by introducing payload validation, refactoring virtual machine configuration models, and strengthening documentation and versioning to support stable SDK generation. Applied C#, TypeScript, and JSON to align naming conventions with .NET standards and redesigned API scope from subscription-level to resource group-level, enabling more granular resource management. Collaborated across teams to refine modeling, improve code quality, and update examples, resulting in a more consistent, maintainable codebase that reduces onboarding time and supports future integrations in cloud environments.
