PROFILE

Roman Safronov

Worked on the openstack-k8s-operators repositories to deliver and refine features supporting NFV telemetry, CI pipeline reliability, and container image management. Developed telemetry metric storage for NFV services, integrating metricStorage configuration through YAML and Kustomize to enhance observability. Later, stabilized telemetry by rolling back metricStorage in line with policy, improving data flow predictability. Enabled registry.k8s.io access in the CI framework, allowing automated deployment and monitoring with kube-state-metrics. Upgraded the Kepler container image in openstack-operator, consolidating configuration for maintainability. Demonstrated skills in Kubernetes, DevOps, and configuration management, with work primarily in Go, Shell, and YAML across multiple repositories.

April 2025 — openstack-k8s-operators/architecture: Stabilized NFV telemetry configuration by rolling back metricStorage. No new features released this month; primary focus was reliability, governance, and cost efficiency of telemetry. The rollback aligns with telemetry policy for NFV deployments and reduces unnecessary storage usage and telemetry noise. Commit d0259fa622b49eab1ffd84543786cf748c2ba453 documents the removal of metricStorage for NFV and targeted changes in va/nfv/ovs-dpdk-sriov service-values.yaml and kustomization.yaml.

Month: 2024-10 — Key feature delivered: Telemetry metricStorage for NFV services (openstack-k8s-operators/architecture). This adds telemetry metric storage, enables metricStorage in service-values.yaml, and ensures creation via kustomization for NFV telemetry improvements (OVS DPDK SRIOV). Major bugs fixed: none reported. Overall impact: improved observability and operational insights for NFV workloads; supports proactive monitoring and performance tuning. Technologies/skills demonstrated: Kubernetes, Kustomize, metricStorage configuration, NFV telemetry, OVS DPDK SRIOV, OpenStack K8s Operators.
