Trey - network engineering & cybersecurity, documented from the lab up.
I build and break networks in the lab so I understand them in production. This site documents my CCNA labs, my Python automation tools, and the security research I do along the way.
edge-router#show projects brief
| Project | Status | Protocol | Description |
|---|---|---|---|
| Lab-OSPF-01 | up | down | Multi-area OSPF topology with route summarization and virtual links (Packet Tracer + real IOS). (In progress.) |
| Py-SubnetCalc | up | up | Python CLI that plans VLSM subnetting from a requirements file - my first automation tool. |
| Py-ConfigBackup | up | down | Netmiko script that backs up running-configs over SSH and diffs them nightly. (In progress.) |
| SOC-HomeLab | up | down | Home SOC: pfSense, Suricata IDS, and a log pipeline for detection practice. (In progress.) |
| CCNP-Security-Notes | admin down | down | Study notes and lab writeups for CCNP Security. (Planned.) |
Status codes: up/up = shipped · up/down = in progress · admin down = planned

I'm a CCNA-certified network engineer with a growing focus on network security. I learn by building: every new topic becomes a lab, and every repetitive lab task becomes a Python script.
Right now I'm deep in routing protocols, VLAN design, and using Python (Netmiko, ipaddress, scapy) to automate the boring parts of network administration. On the security side, I run a small home SOC and write up what I find here on the blog.
