Worked on enhancing the robustness of the API client in the argoproj/argo-cd repository by addressing resource management issues related to HTTP and gRPC connections. Focused on preventing connection leaks by ensuring that response bodies are properly closed on error paths, which improves reliability and reduces operational risk for users integrating with Argo CD APIs. Utilized Go for both the bug fix and the development of comprehensive tests that verify correct resource cleanup across various error scenarios. Applied skills in API development, concurrency handling, and testing to strengthen system stability and maintainability, contributing to more resilient production deployments.
