Back to original languageAbout Nadhir
I help you deploy, stabilize, and automate your Cloud & Kubernetes infrastructure — from architecture to production. Specializing in AWS (EKS, Lambda, IAM, Terraform, Ansible), CI/CD (GitHub Actions, ArgoCD), observability (Prometheus/Grafana — PCA certified) and advanced Linux administration (configuration, hardening, troubleshooting Red Hat/Ubuntu), I work on concrete projects: setting up production EKS clusters, GitOps pipelines, IaC automation, secret security, and cloud cost reduction. 3 Kubernetes certifications (CKA/CKAD/CKS) + AWS SAA + Terraform Associate + Prometheus PCA. I deliver versioned, documented code, ready to be taken over by your teams — not disposable POCs.
