Worked on the circleci/ex repository to finalize an API migration by removing support for GET requests with a body, aligning the API with RESTful conventions. Focused on backend and API development using Go, the changes eliminated deprecated behavior and standardized the HTTP client interface. This cleanup reduced the potential for non-standard usage and simplified edge-case handling, improving both maintainability and client interoperability. By completing the RT-724 migration, the work ensured the API surface area was minimized and future-proofed for ongoing development. The approach emphasized code clarity and adherence to best practices in backend systems, with a focus on robust API design.
