Rockstar🎓
Top SchoolBaptiste Foy is a Senior Software Engineer specializing in fleet automation at Datadog, with five years of experience building resilient, production-grade systems in Go, Kubernetes and Temporal. A CentraleSupélec engineer by training, he has driven remote configuration and update frameworks for the Datadog Agent—contributing notable work on remote-config, TUF/Uptane integration, cache-bypass optimizations and telemetry in a high-scale open-source repo. His background spans SRE, DevOps and full-stack projects, from operating large student networks and OpenStack clusters to founding a gaming platform as a teenager, giving him a pragmatic blend of low-level networking and higher-level software design instincts. He excels at reducing cold starts and improving update reliability for distributed agents, reflecting a focus on operational robustness and developer experience. Based in Paris, he pairs curiosity for systems with a habit of shipping tools people actually use, and off-screen he recharges playing volleyball with friends and family.
