Worked on the ChilliCream/graphql-platform repository to upgrade the service provider registration API surface for GraphQL Platform v16, focusing on enabling smoother customer migrations and future extensibility. The approach centered on delivering new methods for adding application services and diagnostic event listeners, ensuring the API aligned with v16 requirements. Emphasized documentation quality by updating and publishing comprehensive migration guides in Markdown, clearly outlining steps and edge cases for transitioning from v15 to v16. Leveraged skills in software architecture and technical writing to enhance maintainability and clarity, prioritizing robust documentation and API design over bug fixes during this development period.
