About

Network Engineer with 5+ years managing multi-vendor infrastructure — routing, switching, firewalls, and VPN architecture — for over 100 enterprise clients across regulated industries. I hold a CCNA and a Master's in Cybersecurity, and I focus on building networks that are both performant and genuinely secure.

Day-to-day I work across Cisco and Fortinet for routing and switching, Forcepoint NGFW/IPS and FortiGate for firewalls, SentinelOne for endpoint detection, and Proxmox for virtualization. Compliance and data loss prevention via Forcepoint DLP are also a regular part of the job.

Interests

Outside of work I run a personal homelab built around a Proxmox hypervisor. It's where I experiment with secure network segmentation, self-hosted services, and tools like Kali Linux — a direct extension of the work I do professionally, just with more freedom to break things and learn from it.

Away from a screen I spend time fishing, snowboarding, and golfing.

Homelab

Used daily as a testing ground for new technologies and a hands-on learning environment for virtualization and network administration.
