    I’m a Network Engineer and Graphic Designer with over 7 years of experience in network infrastructure and visual communication.

    I am a Senior DevOps Engineer and Cloud Architect with over 14 years of deep expertise in Linux System Administration and Infrastructure. Originally trained in Physics, I bring a scientific, analytical approach to solving complex IT problems—I don't just maintain systems; I understand the "physics" of how they break and how to make them resilient. My career has evolved from the trenches of Help Desk support to founding my own IT service agency, and now tackling global-scale cloud challenges. I am currently pursuing an MSc in Computer Engineering to bridge practical experience with advanced theory. Core Competencies: - Cloud Platforms: Microsoft Azure, AWS - Infrastructure as Code (IaC): Terraform, Ansible - Containerization & Orchestration: Docker, Kubernetes - Observability: Prometheus, Grafana, ELK Stack - OS: Deep Linux System Administration mastery Whether you need to migrate to the cloud, automate your infrastructure, or stabilize a chaotic environment, I bring the patience of a father of twins and the precision of an engineer to get the job done right. mindre
