Who are you

Introduction.

Jรฉrรฉmy Chabernaud
“

Passionate about technology and self-taught, I stand out through my autonomy, curiosity, and ability to quickly grasp new technologies. Teamwork is also a major strength of mine. My interest in blockchains, development (Python & Golang), and AI constantly drives me to explore and master innovations in this rapidly evolving field.

Kubernetes Enthusiast

Cloud-native ecosystem.

I build and operate production Kubernetes platforms end-to-end โ€” from networking and security to GitOps delivery and full observability.

Kubernetes logo Kubernetes
Cilium

CI/CD & GitOps

ArgoCD and FluxCD for declarative deployments. Every change goes through Git โ€” infrastructure as code, always auditable.

Observability

Prometheus, Thanos, Grafana, Loki, Mimir and OpenTelemetry โ€” full-stack visibility from metrics to traces to logs.

Networking with Cilium

eBPF-powered networking, service mesh, and network policies โ€” high-performance connectivity with deep kernel-level visibility.

Security with Tetragon

Runtime security enforcement via eBPF โ€” process-level observability, syscall filtering, and real-time threat detection without sidecars.
