Summary
👤
Senior🎓
Top SchoolJulien Leloup is a Staff Site Reliability Engineer based in Paris with nine years of deep experience across cloud, systems and networking, now shaping reliability at Doctolib after senior roles at GitGuardian, Shadow and Talend. He blends hands-on platform engineering—Kubernetes, GitOps, Prometheus/Thanos, Terraform, Helm—and cloud best practices on AWS/Azure with technical leadership building production-ready core services and observability stacks. Julien’s background in IaaS and telecom-grade monitoring gives him a systems-level view that informs pragmatic SLOs, alerting and on-call practices for large-scale services. He is equally comfortable defining infrastructure-as-code and leading teams to deliver GitOps-driven CI/CD pipelines and service mesh/traffic management. Colleagues describe him as a curious technologist who values software design and human-centered outcomes—off the clock you’re more likely to find him on a West Coast Swing dancefloor.
