I design, automate, and secure hybrid cloud infrastructures using open-source tools. With 18+ years in systems and network engineering, I specialize in CloudOps and DevOps solutions that are stable, scalable, and secure. For over 8 years, I’ve led operations for data centers running open-source IaaS, and more recently have deployed hybrid and private clouds using Kubernetes, Proxmox, and Harvester. Whether it’s optimizing cloud cost, improving high availability, or automating infrastructure, I bring deep hands-on experience and reliability to every project.
