I build production-grade LINE automation systems that turn a regular LINE account, personal or official, into a fully managed bot.

What's included:

Login via QR code or email/password, with persistent sessions

Automated responses (command-based and trigger-based), full message-type support (text, audio, video, images)

Flex Message design for rich, interactive replies

Group broadcasting, automated notes and album posting

Group management: member info, moderation, invite/kick handling

Square bot automation for LINE Square communities

Customer-service and public chatbot workflows

Built for reliability, not demos: These run on Python with a Redis-based queue and dispatch system to prevent message loss under high traffic. Since some integrations use LINE's unofficial API, I monitor network traffic and update the integration whenever LINE changes endpoints, so your bot doesn't silently break.

I also handle deployment and hosting on production Linux servers, so you get a working bot, not just source code.

Let's talk about what you need automated.
