Software engineer based in Tainan, Taiwan. I build LINE and chat bots, workflow automation, and small AI knowledge tools for small businesses — systems that answer the same customer questions every day, send the reminders nobody remembers, and keep team knowledge searchable.
- LINE customer-service bots — FAQ auto-replies, opening hours, hand-off to a human when the bot can't answer, and optional AI answers that stay inside your FAQ.
- Workflow automation — form to spreadsheet, due-date and payment reminders, weekly reports, with notifications on LINE, Telegram or email.
- Team knowledge bases — turn group chats and documents into a searchable knowledge base in Notion or Markdown.
- Backends and integrations — Python and TypeScript services, PostgreSQL, Docker deployments, webhooks and third-party APIs.

- Plain-language scope, price and timeline before any code is written.
- You can test a working version before it goes live.
- You get the source code and setup docs. No lock-in.
