Hi, I’m Dean.
Amateur radio operator (VK4DSB) and IT security professional based in Bellmere, QLD. I spend my time tinkering where my three main interests overlap — radio, security, and AI.
- 📻 RadioLicensed as VK4DSB in QG62. Active on FT8, APRS, and SSTV with a Xiegu X6100, and currently deploying solar-powered Meshtastic relay nodes around northern Brisbane.
- 🛡️ Technology & SecurityMy day job is digital forensics, incident response, and threat intelligence. Off the clock I build open-source DFIR and threat-intel tooling.
- 🤖 AILocal and cloud LLMs run through nearly everything I make — RAG pipelines, natural-language tooling, and offline inference over radio. The aim is useful, not flashy.

My solar Meshtastic node SunBird was slowly losing its battery due to poor sun exposure. Here's how I rebuilt it with a gutted Bunnings solar floodlight for a bigger battery, bigger panel, and a new home on the hill.
