Worked on deprecating the outdated genomic recommendations system in the artsy/metaphysics repository, focusing on backend development and API lifecycle management. The approach involved updating the GraphQL schema to clearly mark the gravity loader as deprecated, adding detailed code comments, and documenting the rationale to assist downstream clients. By guiding users toward the new artworkRecommendations alternative and outlining a phased migration path, the work aimed to reduce technical debt and ensure a smooth transition. Leveraged GraphQL and TypeScript to implement these changes, prioritizing maintainability and clear communication for future development and client integration without introducing new bugs or regressions.
