Something about myself
Technology enthusiast turned Systems Administrator with a passion for building robust infrastructure. I work with a variety of Linux distributionsâUbuntu, Debian, and Red Hatâdeployed across bare metal servers, virtual machines, and containerized environments.
My day-to-day involves designing and managing hybrid cloud solutions, Kubernetes clusters, and enterprise security implementations. From VMware ESXi to Proxmox virtualization, and from Docker orchestration to Terraform infrastructure as code, I focus on creating systems that are secure, scalable, and reliable.
At home, I maintain an active lab environment where theory meets practice. This homelab serves as my testing ground for new technologies, configuration experiments, and the source of many tutorials shared here. It’s where professional curiosity transforms into hands-on expertise.
As an ISO/IEC 27001 Internal Auditor and certified DevOps Engineer, I believe that great infrastructure isn’t just about cutting-edge technologyâit’s about security, compliance, and continuous improvement.
