Production AI Systems
Plus the Application Around Them
We build retrieval systems, AI agents and fine-tuned models, and the Laravel applications around them, for Australian businesses. Based between Australia and Southeast Asia.
About
DreamFast Solutions Limited is a Hong Kong registered company led by Nathan Sapwell, an AI engineer and full-stack developer. For over a decade Nathan has shipped production software for businesses of all sizes, from custom web applications to the server infrastructure they run on.
The core work today is AI: retrieval systems, AI agents and fine-tuned models, integrated into real applications. That sits on top of a decade of Laravel and PHP delivery, Vue.js and React frontends, and Linux server administration.
Nathan has maintained a 100% job success rate on Upwork for over eight years, and releases open source LLM work on Hugging Face with tens of thousands of downloads. He works between Australia and Southeast Asia, on Australian business hours.
