Available to hire
I am Linh Nguyen, a dedicated infrastructure automation expert with 10+ years of hands-on experience building scalable, secure cloud platforms on AWS and Azure. I specialise in Terraform modules, Ansible configuration management, containerization with Docker, and Kubernetes orchestration, and I’ve engineered CI/CD pipelines using Jenkins and GitLab to accelerate delivery.
I thrive in agile teams, collaborate across disciplines, and enjoy mentoring colleagues as I help organisations adopt GitOps, Istio service mesh, and secure secret management with HashiCorp Vault.
