Raphaël Bizos
Raphaël Bizos is a Staff Site Reliability Engineer at Criteo, where he has maintained the company's observability stack and SDKs since 2020. He led the migration of Criteo's metrics from Graphite to Prometheus, and is currently moving its internal metrics SDK to OpenTelemetry, work that has taken him upstream into Prometheus itself, contributing native histogram migration tooling and the OpenMetrics 2.0 parser. Outside of work, he lives in the forest of Fontainebleau, where he spends as much time as he can bouldering and exploring the rocks with his two dogs.
