Worked on the buildkite/agent-stack-k8s repository to enhance build traceability within Kubernetes-based CI/CD workflows. Developed a feature that adds Kubernetes Job annotations to capture build context, specifically storing the repository URL and pipeline slug as metadata. The implementation involved updating the scheduler to read these values from environment variables and introducing constants to standardize annotation keys, reducing manual errors and simplifying future maintenance. Leveraged Go and Kubernetes to deliver this improvement, which increases observability, auditability, and governance for CI runs. No critical bugs were reported during this period, reflecting a focused and stable development effort on feature delivery.
