IT Infrastructure & Systems Administrator

Hi, I'm Arif Ali.
I build infrastructure
that stays up.

I design, deploy, and secure networking, cloud, virtualization, and messaging infrastructure — from Exchange Server and Active Directory to AWS, WireGuard VPN, and OPNsense firewalls.

This site is self-hosted on my own Proxmox + RHEL infrastructure — right now.

About

I'm an IT infrastructure professional with hands-on, real-world experience building and securing complete environments end to end — not just following documentation, but designing solutions to genuinely hard problems, like routing around an ISP-level port block using a cloud relay and a VPN tunnel.

What I do: I administer Windows Server & Active Directory environments, deploy and harden Microsoft Exchange Server, build secure network perimeters with OPNsense and WireGuard VPN, run virtualized infrastructure on Proxmox with Red Hat Enterprise Linux, and work across AWS cloud services to extend on-prem infrastructure.

How I work: I like to build things I can fully explain. Every project on this site was designed, deployed, and troubleshot by me personally, in a self-built home-lab environment running production-grade services — including the page you're reading right now.

I'm currently looking for an opportunity to bring this infrastructure, networking, and systems administration experience to a team. See the full write-ups on my Projects page, or reach out below.
