About

Operational profile

I’m Mahabub Subhany, a System Administrator based in Perth, WA. I work across Microsoft 365, Active Directory / Entra, Intune, Hyper-V, networking, and operations — with a strong preference for automation, clean documentation, and security-first thinking. Off the clock I run a self-hosted homelab on ZimaOS and OpenWrt, and build small tools that fix real problems.
