Hi, I’m Peter Johnson, a Principal Security Engineer, systems programmer, and founder of One Red Dog Media based in Melbourne, Australia.

Over the past 30+ years, I’ve engineered software across the entire computing stack: from bare-metal embedded assembly, console game engines, and PCIe kernel device drivers to real-time audio DSP, enterprise cloud architecture, and modern offensive application security.
