About

I've been building software for over 20 years, across mining, resources, government, and cyber intelligence. The throughline in all of it is the same: the systems that matter most are the ones that have to hold up under scrutiny, not just in a demo. At Steltek, I lead the engineering behind Constant, our Essential Eight compliance platform built for organisations with ongoing compliance obligations. Compliance software has a credibility problem. It needs to be accurate, auditable, and defensible, not just automated. I designed Constant's architecture with that in mind, including automated evidence collection, AI-assisted reviews, and workflow logic that keeps certified assessors involved throughout. The result is a platform built with assessors, not assumptions. Before Steltek, I built mission-critical systems for BHP, Anglo American, WorldStack, and others across sectors where failure has real consequences. That background shapes how I approach every engineering decision. If you're working on something complex in platform architecture, compliance systems, or intelligent tooling and want to compare notes, feel free to reach out.
