I'm a software engineer with over a decade of experience, now working as a GenAI specialist — building AI agents that change how enterprise software actually gets built. Before this I was a startup CTO and CEO and a lead AI engineer, so I've shipped real systems end to end, not just slides. I teach the way I wish things had been taught to me: plain, honest, and grounded in what the official documentation and real projects actually show — no hype, no padding. I'm based in Japan and work in both English and Japanese. Whether you're preparing for a certification or you just want to understand how to architect reliable, production-grade systems with Claude, I'll meet you where you are and get you ready.
