Systems we've shipped.
Production builds and proofs-of-concept. Client work is kept private; public repos are linked.
🔗Slack ↔ LINE media bridge
An n8n workflow routing text, images, and PDFs between Slack and LINE for a live 民泊 (みんぱく / minpaku) operation — with format-aware payload handling so nothing arrives broken.
💬Chatwork ↔ Slack threaded sync
Two-way message sync that keeps threads intact across Chatwork and Slack, so a Japanese-and-English team never loses context between the platforms each side prefers.
🧩YouTube Playlist Generator — MCP
A Model Context Protocol server in TypeScript that lets AI agents search, build, and edit YouTube playlists with real API tools — an example of AI wired to actually do things.
🌐Cloudflare Pages hosting pipeline
Deployment groundwork for this very studio — testing Cloudflare Pages against a self-hosted laptop + Tailscale setup to pick the right home for zahan.jp.
🏠Operations automation & daily reporting
Server admin, automations, and Japanese 日報 (にっぽう / daily reports) for a real-estate & lodging business — with the goal of keeping operations under 20 hours a week.
Your operation could be next.
The best case studies start with one annoying, repetitive task. Tell me yours.
