I’m Pedro Liranzo — a Network Administrator and U.S. Army veteran. I started as a 25N Nodal Network Systems Operator-Maintainer with the 59th Signal Battalion in Alaska, running IP-based tactical networks and COMSEC for brigade operations. Since then I’ve built data centers for J.P. Morgan Chase, supported enterprise users at SAIC, and earned a B.S. in Information Technology from William Paterson University.

Today I administer the Army National Guard’s network infrastructure at the Picatinny Arsenal Network Enterprise Center — configuring Cisco routers, switches, and firewalls, hardening systems to DISA STIGs, and supporting ATO certification. I’m happiest automating the tedious parts: I built a database and script that turned hours-long STIG scans into minutes. Off the clock, I run an enterprise-grade homelab — Proxmox, OPNsense, zero-trust access, and a local AI stack — to keep my skills sharp and test ideas before they hit production.
