Worked on the castai/kvisor repository to deliver advanced storage metrics collection for Kubernetes clusters, focusing on both node-level and pod volume observability. Leveraged Go and native Linux APIs to refactor metrics gathering, replacing external dependencies with direct system calls for improved accuracy and performance. Implemented a gRPC-based pipeline for node storage metrics and extended support to PVC-backed pod volumes, integrating Kubernetes context and RBAC controls. Enhanced monitoring reliability by ensuring metrics collection remains functional when eBPF and NetFlow are disabled, and added comprehensive end-to-end tests. The work emphasized backend development, system programming, and infrastructure as code practices.
