Network Infrastructure Specialist | Keifer Hendry

Network Infrastructure Specialist

I build production-grade infrastructure that scales. 14+ years architecting resilient systems, managing IT/OT operations, and solving complex problems under pressure. Proxmox, ZFS, OPNsense, zero-trust networking, and 99%+ uptime are my toolkit.

Featured Projects

Production Homelab Infrastructure

Proxmox VE 8 cluster with 2-node redundancy, ZFS RAIDZ backup, OPNsense firewall, zero-trust networking, and Prometheus+Grafana monitoring. 99%+ uptime across 11 production VMs.
