About

I'm a technical founder and contractor based in Brisbane. I build AI-native systems: voice agents, automation pipelines, CRM architecture, and the infrastructure to run them, for companies that need it done properly and fast.

Background spans managed services, SaaS products, and AI engineering across construction, education, healthcare, and finance. I've worked in environments where systems actually have to work.

Currently running Hanthos, an AI automation consultancy, alongside a CRM SaaS product targeting owner-operated businesses. Open to direct contracts and Upwork engagements.
