Ktatarnikov

Worked on the glaciation-heu/gitops-deployments repository to deliver scalable, automated infrastructure for multi-site deployments and observability. Over four months, built and enhanced CI/CD pipelines using Argo CD and Helm, integrated NATS JetStream for cross-site data replication, and implemented distributed key management with MinIO. Addressed operational stability by restoring Prometheus-based monitoring and fixing deployment misconfigurations in Kubernetes manifests written in YAML. The technical approach emphasized Infrastructure as Code, leveraging Kustomize and GitOps workflows to manage complex cloud-native environments. This work improved deployment reliability, security posture, and real-time visibility into resource usage, supporting robust, auditable, and automated DevOps processes.

May 2025 monthly summary for glaciation-heu/gitops-deployments focusing on observability improvements. Restored monitoring metrics collection for kg-exporter by enabling Prometheus and Kepler-based pod queries for Network, Storage, CPU, RAM, and Energy usage. This reinstates visibility into performance and resource consumption, enabling faster incident response, capacity planning, and SLA assurance.
