馃ぉ
RockstarCyril Tovena is a Senior Principal Software Engineer with 11 years of experience building scalable, distributed systems and observability tooling from Ubisoft to Grafana Labs. At Grafana he led development of AI-driven features like Grafana Assistant and core backend work across Loki, Cortex and Mimir, contributing to widely used open-source projects that power Prometheus long-term storage and profiling systems. He combines deep Go backend expertise with system architecture and DevOps experience鈥攐ptimizing index schemas, query validation, and performance-sensitive ingest paths. Cyril has a track record of shipping infrastructure improvements (schema v11 for Mimir, profiling aggregation in Phlare) and practical tooling (parquet analysis, proto/build automation). Based in Avignon, he pairs hands-on coding with technical leadership, having introduced containerization, CI/CD and cloud patterns at scale. An often underappreciated strength is his blend of game-server/metrics know-how and AI-agent work, bridging realtime systems and emerging ML-driven developer tooling.
