PROFILE
Sjoerd Van Der Meer
Sjoerd van der Meer enhanced the dotnet/aspnetcore repository by improving OpenAPI schema generation and documentation accuracy. Over two months, he refined XML comment propagation and Description attribute handling, ensuring schema references in ASP.NET Core APIs accurately reflect intended documentation without unintended leakage. Using C# and .NET, he addressed issues with nullable types and circular references, preventing empty schemas and improving client generation reliability. His work included adding targeted regression and scenario tests, particularly for data annotation attributes and complex schema relationships. These contributions deepened the robustness of OpenAPI integration, demonstrating careful attention to maintainability and correctness in backend development.
