About Me

I believe in the power of simplicity. Based in Tokyo, I create products that are beautiful, functional, and purposeful. My journey began unconventionally— self-taught, driven by curiosity and a desire to build things that matter.

Now I lead BreakAI, building AI-powered solutions with a focus on elegant design. I also conduct research in multi-agent systems at AIST and advise companies on technology strategy.

Open source contributor to Rust, Material UI, and Zig. I find inspiration in the intersection of technology and Japanese aesthetics—where less becomes more.
