Full-Stack Software Engineer

Brisbane, AustraliaAvailable for new roles

I’m a full-stack engineer with 4+ years of experience building mobile, web, and backend products, backed by 1.5 years in QA. I enjoy taking ideas from early discussions all the way to production—pairing solid architecture with thoughtful UI/UX, and using AI-agent workflows to build and iterate faster.
