# Deploying networks. Securing systems. Automating everything.

~> docker compose up -d sudo hire-me

I’m Jonathan Dunphy, a self-taught network and systems technologist. I design, secure, and automate infrastructure using Linux, Docker, and open-source tools.

Terminal

I live in the command line. From configuring SSH keys and routing tables to running diagnostic tools like top, netstat, tcpdump, and wireshark.

Servers

Experienced in deploying and securing web and mail servers on AlmaLinux and Ubuntu. I’ve configured OpenLiteSpeed, hardened systems with Lynis, and automated backup workflows.

Docker

I use Docker to build modular, reproducible environments. From Portainer to Compose stacks, I containerize services for testing, monitoring, and automation.

Hands-On Learning

My approach is simple: learn by building. I’ve created full production stacks, hardened live VPS instances, and configured DNS, SSL, and firewall rules from the ground up. Every project is a new lab; every problem, a chance to learn.
