Worked on backend and DevOps improvements across two repositories, focusing on maintainability and reliability. In Nordix/baremetal-operator, removed deprecated ControllerManagerConfig and obsolete YAML files, updating kustomization to align with the latest controller-runtime. This cleanup reduced maintenance overhead and improved upgrade compatibility using Kubernetes and YAML. In langgenius/dify-official-plugins, addressed API integration challenges by updating the OpenRouter plugin to parse reasoning content from the correct API field, ensuring resilience to upstream changes. Leveraged Python and plugin development skills to deliver targeted fixes, demonstrating a methodical approach to evolving codebases and maintaining stability in response to external API modifications.
