NHÀ propos de Narjess
DevOps Engineer with 7 years of experience in cloud-native systems, CI/CD automation, and Infrastructure as Code (Terraform, GitOps). I bring strong expertise in Kubernetes, Docker, GitLab CI/CD, Jenkins, and DevSecOps practices, combined with a solid background in computer science and software development. I have designed and delivered scalable, secure, and automated infrastructures that support millions of users across different environments. Curious and driven, I’m passionate about building systems that last, applying modern technologies to solve complex challenges, and continuously learning through research and collaboration.
Current focus and interests: Cloud-native architecture, Infrastructure as Code (Terraform), CI/CD pipelines, DevSecOps, container orchestration, and secure, scalable infrastructure systems.
