Worked on deployment and configuration reliability for the uber/cosmo repository, focusing on stabilizing rollouts and improving maintainability. Addressed a critical bug by ensuring health probes reference the correct service or container port as defined in Helm values, which enhances deployment correctness. Improved observability and runtime consistency by updating OpenTelemetry collector mounting to use a dedicated volume name, and clarified router configuration with an explicit config path to reduce misconfiguration. Refined Helm templates to consistently set image versions in application labels, supporting better environment management. Utilized DevOps practices, Helm, Kubernetes, and YAML to deliver targeted improvements that strengthen deployment workflows.
