About

I'm Koji Kawamura, a software engineer based in Tokyo. I'm VP of Technology at a Japanese SaaS company building AI-native FP&A software where I oversee technology strategy and AI infrastructure.

Before that, I was CTO at a Japanese AI startup, where we built generative language models on NVIDIA A100s for automated creative production along with a numerical optimisation system for ad delivery. After the startup joined a larger Japanese group, I led the development division within the group's technology subsidiary.

I write about the runtime side of agentic systems and about building and leading engineering teams. Longer Japanese versions of some posts appear on Zenn.
