À propos
Introduction
J'ai piloté la supervision de 300+ applications en production via Prometheus, Thanos, Grafana, Loki et OpenTelemetry. J'ai automatisé les pipelines d'alerting (-70% de temps de config), migré les architectures de logs vers des pipelines distribués (-40% de latence) et déployé une approche GitOps complète avec ArgoCD sur Kubernetes. Je cherche une mission freelance sur des environnements critiques à forte volumétrie.
