Mission, BC — Open to work

Avninder Sran

$  |

6+ years in enterprise IT, network security, and infrastructure. CCNA & Enterprise Core Specialist certified. I have spent the better part of my career digging into the hard stuff — escalations, root cause analysis, lab reproductions — and I am ready for what comes next.

A bit about me

Most of my career has been at Sophos, where I worked my way from technical support up to Global Escalation Engineer. That meant owning the most difficult cases — deep dives into firewall behavior, VPN edge cases, authentication failures, routing anomalies. I worked directly with product and development teams when bugs needed reproducing.

Outside of work I run a homelab on Proxmox with Windows Server, Linux VMs, Ubiquiti networking, and a NAS with automated backups. It is less of a hobby and more of a habit at this point.

I am currently looking for my next role — something in sysadmin/infrastructure, network engineering, customer success, or solutions engineering. I thrive in environments where the technical bar is high and the work actually matters.

What I run at home

The homelab started as a way to keep skills sharp and turned into something I genuinely enjoy. Here is what is currently running.

Proxmox Hypervisor

NUC-based home server running Windows Server and Linux VMs, LXC containers, and self-hosted services. Keeps me hands-on with sysadmin work outside of any job.
