Real production systems, not demos.
I ship. These are the kinds of systems I design, build, and maintain in production.
Workflow Automation
Slack↔LINE media bridges routing text, images & PDFs. Chatwork↔Slack threaded sync. Custom n8n nodes, webhooks, and JSON payload wrangling.
MCP Servers
Built a YouTube-playlist-generator MCP server in TypeScript — extending what AI agents can actually do with real tools.
Infrastructure
ConoHa VPS, Docker Compose, Cloudflare DNS/routing, Hostinger. Server admin that keeps automations running quietly and reliably.
Comms Platforms
Deep integrations with Slack, the LINE Messaging API, and Chatwork API — bridging teams that live in different tools.
Beppu Home
Automation & dev for a Japanese real-estate / 民泊 (みんぱく / minpaku) lodging business in Oita — plus Japanese 日報 (にっぽう / daily reports).
Smart Environments
Custom Apple Music & YouTube integrations driven through Nest Hub and smart devices — automation that reaches into the physical space.
