Jordy Pee enhanced the ChilliCream/graphql-platform repository by extending its source generation pipeline to support internal members within ObjectType and InterfaceType definitions. Using C#, GraphQL, and Roslyn-based source generators, Jordy addressed a limitation that previously restricted code generation to public members only. This update allowed the platform to generate more complete and flexible types, reducing the need for manual schema adaptations after code generation. By carefully handling C# internal and public accessibility, Jordy ensured backward compatibility while increasing the robustness of client integrations. The work demonstrated a solid understanding of backend development and modern code generation techniques within the .NET ecosystem.
