I specialize in DNS management, system administration, and infrastructure automation. With hands-on experience across Linux servers, Cloudflare, Microsoft 365, and Docker, I help organizations maintain reliable, secure, and well-automated infrastructure. I write about the tools and techniques I use daily — from server hardening to workflow automation.
