I am a principal consultant operating through Brumbiesoft (ABN 95 290 253 114). My focus is the design, delivery, and assurance of software-intensive systems in environments where the cost of failure is measured in lives, missions, or regulatory penalty.
My career started in 1995 with an internship at Honeywell Military Avionics Division on the RAAF AP-3C Orion, followed by Sydney Rail SCADA software at CAE Australia and mortgage origination software at FANMAC. In 1998 I joined Boeing Australia to develop Ada code for the Collins-class submarine combat system's weapon data computer, then integrated the AGM-142 standoff weapon on the RAAF F-111. In 2001 Boeing Australia seconded me to Seattle, where I spent the next six years on the RAAF Wedgetail mission system as lead designer for frequency management and lead engineer for SATCOM integration.
I stayed in Seattle for another thirteen and a half years. At Crane Aerospace I led sensing software for the Boeing 787 Brake Control Monitoring System, developed to DO-178B Level A. At Performance Software I worked as a senior principal engineer, project lead and team manager across avionics and medical programmes: Boeing 737 Next-Gen FMS, Boeing 747-8, Airbus A220, A330 and A350 APU, and the Stryker / Physio-Control Tesla defibrillator. Most of that avionics work was at DO-178B/C Levels B and C.
In 2021 I returned to Australia and joined Insitec's Military Intelligence and Space business, managing up to 20 engineers delivering tactical-edge devices and command-and-control and blue-force tracking systems for the Australian Army and emergency services. From late 2025 I headed software and AI for CitadelEdge's Defence and National Security Solutions division, full-time and then on contract until mid-2026, and later in 2026 I was AI Architect at Erin Living Technologies.
Today I run Brumbiesoft as an independent practice. Recent engagements include officer-safety and law-enforcement apps, a multi-domain military C2 simulator, AI implementation consulting, and AI-augmented project management product development. The discipline that defence and aviation taught me — requirements rigour, traceability, independent verification, configuration control — is exactly what AI agent teams need to be productive without becoming dangerous. That convergence is the work I'm most interested in right now.
