About
I'm Matt Harrison, a prototype and R&D engineer based in Melbourne, Australia.
I build practical systems across hardware and software, from mechanical design, electronics and firmware through to apps, web tools, data processing and AI-assisted workflows.
My work is usually at the point where physical products meet digital systems. That can mean designing a mechanism, bringing up a PCB, writing firmware, building a control interface, processing sensor data, debugging a field issue, or turning a rough prototype into something that can actually be used.
I've worked on rugged inspection hardware for underwater, tunnel and infrastructure environments, where reliability matters and the problems are rarely neat.
Outside my day job, I build my own hardware and software projects. I'm especially interested in products that combine sensors, physical interaction, data and useful interfaces.
My path has been self-directed. I learned by building, breaking, debugging and shipping real things.
I care less about fitting into a neat category and more about making systems that work in the real world.
