Yanze Dai (Grant Dai)

Software engineer in Tokyo, writing about AI, software, systems, and long-term growth.

Hi, I'm Grant, a software engineer based in Tokyo. I've been developing software since 2015, with experience across frontend and backend engineering as well as big data systems. Today, my focus is on using AI to empower people and improve how we build software.

Over the years, I've worked across frontend development, platforms, and infrastructure. I'm currently working at Fast Retailing, where I help build software for global commerce.

Outside of work, I enjoy building open-source projects and exploring how AI is changing the way we create software. I'm working on Syndroo, an experiment in owning your content and sharing it across the web.

I write about software, AI, learning, and life as a builder on grant-dai.com. My interests go beyond code: I'm curious about the tools, ideas, and habits that help people keep growing.

Most of what I build is available on GitHub. You can also find me on X or connect on LinkedIn.
