Hi there! I’m a Senior Full-Stack Engineer based in Perth with a rather unique blend of 14 years of hands-on production shipping experience and a PhD in Electrical and Computer Engineering. Over the years, I’ve had the privilege of building high-impact, scalable software across a variety of fascinating industries—from mission-critical rail automation systems at Hitachi Rail to secure, high-traffic digital health marketplaces and telehealth platforms at HealthEngine and Coviu Global. I genuinely love the entire lifecycle of product creation, whether that means mapping out robust backend architectures, designing seamless user interfaces, or launching native mobile apps directly to the stores. For me, great engineering isn't just about writing clean, testable code; it’s about collaborating with close-knit, high-ownership teams to solve real-world puzzles that make a tangible difference in people's lives. I consider myself a pragmatic builder who thrives in agile environments where I can take an ambiguous concept and turn it into a reliable, well-documented system. When I’m not diving deep into database schemas or exploring the responsible use of assistive AI tooling to accelerate development workflows, you can usually find me sharing context with my teammates, mentoring peers, and looking for new ways to raise the engineering bar together.
