Cybersecurity graduate and service member with a passion for networking, self-hosted infrastructure, and hands-on security.

About

Husband.   Soldier.   My Family’s SysAdmin.

  • Built a multi-VLAN home network from scratch using pfSense and two managed switches — six VLANs, default-deny firewall rules
  • Run a full Docker stack on Ubuntu Server — Jellyfin, Jellyseerr, Homarr, Nginx Proxy Manager, Uptime Kuma, Portainer, Home Assistant, and this website
  • Access everything remotely through Tailscale running as a subnet router on my home server
  • Hands-on offensive security practice through HackTheBox and TryHackMe

B.S. Cybersecurity Technology — University of Maryland Global Campus

Currently pursuing CompTIA Security+

6 VLANs configured
8 self-hosted services

Projects

Networking

Homelab Network

Repurposed three HP ProDesk 600 mini PCs into a full homelab stack.

  • PC #1 — pfSense router/firewall
  • PC #2 — Ubuntu Server running Docker containers
  • PC #3 — LMDE workstation with pentesting VMs
  • Multi-VLAN network with inter-VLAN firewall hardening
  • Tailscale for secure remote access from anywhere
Wireless Security

Wardriving Pi

Built a Raspberry Pi wardriving rig with a touchscreen that automatically boots Kismet on startup for passive wireless network reconnaissance.

  • Raspberry Pi with touchscreen display
  • Alfa wireless adapter for monitor mode capture
  • GPS puck for location tagging
  • Kismet auto-launches on boot
Live

Self-Hosted Website

Migrating marcnims.com off Cloudflare Pages into a Docker container on my server, served through Nginx Proxy Manager and exposed via Cloudflare Tunnel.

  • Docker container on my server
  • Nginx Proxy Manager — reverse proxy + TLS
  • Cloudflare Tunnel — no port forwarding needed
Home Media

Jellyfin Media Client

Firestick died. Grabbed a Pi 4B and turned it into a Jellyfin client instead.

  • Raspberry Pi 4B running LibreELEC + Kodi
  • Jellyfin for Kodi — streams from my server on G5
  • Hardware H.265 decode — no transcoding needed
Wireless Security

WiFi Pineapple Clone

Turned a GL.iNet GL-AR750 travel router into a WiFi Pineapple clone for wireless auditing and rogue AP testing.

  • GL-AR750 flashed with wifi-pineapple-cloner
  • Rogue AP and deauth capabilities
  • Portable wireless auditing platform
  • Open-source firmware build
In Progress

Bad USB — Pi Zero W

Turning a Raspberry Pi Zero W into a bad USB device that emulates a keyboard and executes payloads on Windows 11 targets the moment it's plugged in.

  • Pi Zero W in USB gadget mode as HID keyboard
  • Payload delivery — RAT injection, credential harvesting, or malware drop
  • Targeting Windows 11 — most common attack surface
  • Built for security research and authorized testing
In Progress

Home Assistant

Home Assistant in Docker for local home automation — door sensors, motion sensors, and smart lights, all without cloud dependency.

  • Docker container on my home server
  • VLAN 20 isolation
  • Integrated with pfSense firewall rules
In Progress

Leave-Behind Pi

Raspberry Pi 4B running Kali Linux configured as a drop device — plug it into a network and walk away. Built for persistent access and wireless attacks from inside the target network.

  • Pi 4B 4GB RAM running Kali Linux
  • LAN drop — direct plug-in for persistent network access
  • Remote access via Tailscale — phones home on boot
  • Full Kali toolset available remotely once inside
Coming Soon

Frigate NVR

IP camera system using Frigate running in Docker on my server, with recordings stored on dedicated storage and isolated on its own CAMERAS VLAN.

  • Frigate — Docker container on my server
  • VLAN 40 camera isolation
  • PoE switch for camera power
  • No internet access — local only
