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 at Honeywell Military Avionics Division, then CAE Canadian Aviation Electronics and FANMAC Financing, before joining Boeing Australia in 1998 to develop Ada code for the Collins-class submarine combat system's weapon data computer. In 2001 I moved to Seattle to lead frequency-management design on the RAAF Wedgetail mission system for the next six and a half years, then stayed on in Seattle for another thirteen and a half years across avionics and medical work — Boeing 737 Next-Gen FMS, Boeing 747-8, Boeing 787 brake control, Airbus A220, A330, A350 APU, Bombardier C-Series, Honeywell next-gen FMS, and the Stryker / Physio-Control Tesla defibrillator. The Boeing 787 brake control system was DO-178B Level A; most of the rest was Levels B and C.
In 2021 I returned to Australia and joined Insitec's Military Intelligence and Space business, leading software teams delivering tactical-edge devices, blue-force tracking systems, and perimeter security products for the Australian Army and allied agencies.
Today I run Brumbiesoft as an independent practice. Recent engagements include officer-safety platforms for state law enforcement, bid-support for defence research organisations, 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.
