From the Roads to
the Red Team

I'm a truck driver by day, cybersecurity student by night — actively transitioning into the security industry. Currently studying Certificate IV in Cybersecurity at TAFE SA, with a deep focus on offensive security and penetration testing.

What sets me apart from most beginners? I don't just study theory. I have a serious home lab — Proxmox clusters, SDR equipment, a Flipper Zero, WiFi Pineapple, and more — and I use it to actually break and understand things.

My background in RF and hardware hacking is a rare specialisation at my level. I'm working toward certifications including the eJPT, PNPT, and eventually OSCP while building my YouTube channel and public profile in the community.

Built, Not Just Studied

Real hardware, real networks, real skills. These aren't simulated labs — they're physical builds.

🍓
Kali Pi-Tail
Waveshare CM4-NANO-A Build

A portable, pocket-sized Kali Linux device built on a Compute Module 4 with the official Pi-Tail image. Designed for discreet network assessments and on-the-go testing.

📡
SDR RF Lab
HackRF + Mayhem Firmware

Full RF security research setup using HackRF One (Mayhem firmware), RTL-SDR, and Evil Crow RF V2. Used for signal capture, replay analysis, and RF protocol research.

🐾
Pwnagotchi
