Mark Poko developed and maintained core features for the grafana/cloudcost-exporter and grafana/synthetic-monitoring-agent repositories, focusing on cost attribution, cloud integration, and developer experience. He implemented tenant-level cost attribution using Protocol Buffers and Go, automated dashboard provisioning with shell scripting and Makefile, and enhanced CI/CD security through GitHub Actions. Mark improved cloud cost accuracy by supporting GKE ARM and HyperDisk pricing, streamlined onboarding with updated documentation, and enabled privacy-preserving telemetry in the synthetic-monitoring-agent. His work demonstrated depth in backend development, configuration management, and system monitoring, consistently delivering maintainable solutions that improved reliability, observability, and operational efficiency across cloud environments.

October 2025 monthly summary: grafana/synthetic-monitoring-agent. Delivered tenant-level cost attribution labels, enabling centralized cost tracking at the tenant level and simplifying attribution from individual checks to the tenant scope. This included extending the Tenant protobuf to add a slice of strings for cost attribution labels and applying the change across the agent (commit cf8f74603c188f61900b01d27d8b7c857ec856d5).
