Black Cat Notes
SubscribeI’m Kuroneko — building in public. After years working with Japanese companies across manufacturing and IVD for the China market, I pivoted into AI and indie making to ship practical, calm software.
Here I share short takes on AI/product, notes from hands‑on work, and experiments in AI productization, iOS apps & small games, Rust tools, and Python data plumbing. Learn more on my About page.
On the side, I run a visual branding experiment — anime & aesthetic illustration curated at art.kuroneko-cmd.dev.
