Sam Joyce
I design and build software products and AI systems.
My work spans product design, web and mobile applications, native desktop software, backend services, and infrastructure. I fine-tune and evaluate language models, build systems that coordinate AI agents, and integrate AI into software products.
Role
I’m Lead AI Engineer at Pluss Communities, based in Australia.
