Gopisivanappan Vasanthi developed comprehensive Swagger-based API documentation for the Polaris Gateway Azure Function, focusing on enhancing API discoverability and integration within the CPS-Innovation/Polaris repository. By implementing extensive OpenAPI attributes across endpoints in Case Work, Exhibit Producers, and House Keeping applications, Gopisivanappan ensured that client applications could reliably interact with the APIs. The work involved using C# and Azure Functions to establish a reusable documentation foundation, while also addressing build errors and refining exception handling for consistent API responses. This approach improved maintainability and set the stage for scalable future enhancements, demonstrating depth in API development and documentation practices.
