Rockstar🎓
Top SchoolGeorge Robinson is a Senior Software Engineer II based in England with five years of focused experience building resilient, back-end systems for observability and edge infrastructure. He currently contributes to Grafana Loki and previously improved Grafana Alerting and Prometheus Alertmanager, adding metrics, UTF-8 support, and robustness features that enhance monitoring and alerting at scale. Before Grafana he engineered L7 firewall services at Cloudflare, leading the design of the Rulesets API and real‑time matching logic, and earlier built highly available deployment and monitoring tooling using Go and Raft. He combines deep distributed-systems know-how with practical API and telemetry improvements, often shipping subtle reliability fixes like backoff strategies and thread-safe template handling. Colmpleted an MSc in Computer Science at UCL, he’s an active open-source contributor whose work touches widely used projects in the observability ecosystem.
