Hi, I'm Kotaro Furuno

Independent engineer and founder at TechWorker Inc. (Tokyo). I build AI products and keep a foot in open source.

Building & maintaining

  • japan-synthetic-personas — 3,000 statistically-grounded synthetic Japanese consumer personas (CC BY 4.0). Dataset on Hugging Face.
  • AI agent operating layer — my daily driver runs on gbrain (persistent agent memory) and gstack (opinionated build workflow), with local patches and version discipline.

Contributing to

  • gbrain — persistent memory for AI agents. Three fixes adopted upstream and credited in the release notes:
    • v0.60.5.0 — the session-end hook skips gbrain's own claude-cli sessions (#5468), and recall --grep filters before its limit (#5619).
    • v0.56.1.0 — a conversation-parser pattern for Python-dict transcripts (#5365).
