About
Tokyo-based software engineer and AI adoption consultant at haya Inc. I help teams redesign workflows, validate AI use cases, and ship useful products, from pilots through production rollout.
I also build practical developer tools:
• BlobDive — a Rust CLI for bounded, read-only inspection of nested software artifacts.
• MCP Erabi — Japanese search and comparison of connection requirements in the Official MCP Registry.
• Kata Prompt — a local-first workbench for assembling and reusing Japanese prompts.
Tools I use include Codex, Claude, Cursor, OpenClaw, and MCP.
Happy to compare notes on agent tooling, MCP integrations, AI evaluation, and getting AI workflows adopted. Feedback from developers working with unfamiliar artifacts or Japanese-language AI workflows is especially welcome.
