I work across IT infrastructure, systems administration and cybersecurity, with a strong focus on self-hosted environments and practical operations.
My work includes Linux and Windows administration, identity and access management, networking, DNS and mail infrastructure, monitoring, incident handling, troubleshooting and automation. I also develop and maintain projects under the iTELade organization.
