I studied materials, where metals don't break all at once: they give way one row of atoms at a time. I build software the same way, in small verified steps.

• Building CommerceAgent, a self-hosted Claude Code workbench reachable from the browser and seven messaging channels.
• Building 康养日记, a WeChat Mini Program that keeps elderly patients on their medication schedule and tells their family when they fall off it.
• Exploring agent systems, MCP apps, developer tooling, and self-hosted software. Open to thoughtful collaboration on useful open-source projects.

Projects I started and maintain myself, the work I would want you to read first.

A self-hosted, multi-user, agent-first Claude Code workbench: one agent, workspace, and automation set, reachable from the browser and seven messaging channels.

• Wraps the Claude Agent SDK for TypeScript into a long-running service shared across Feishu, Telegram, QQ, DingTalk, WeChat, Discord, and WhatsApp.
• Tasks execute on the host or inside Docker sandboxes, with an explicit ACL matrix and CI on every push.
• Desktop builds bundle the backend, the web UI, and a Node runtime into a single Electron app, so installing it needs neither Node nor a database.

Scheduled reminders, automatic missed-dose records, and a family alert after three missed doses in a row.

• Two scheduled cloud functions carry the whole reminder pipeline, a 5-minute reminder pass and a 10-minute missed-dose pass. Each is idempotent through its own log collection, so a retry never double-notifies a family.
• The "three missed doses in a row" streak is computed over a total order (business time, then create_time, then _id), so the verdict cannot flip with the database's return order.
• Timezone-safe by construction: the cloud runs on UTC and the client derives "today" in Asia/Shanghai, so the task list and the reminders cannot disagree by a day.
• Every query is owner-scoped and paged past the platform caps (100 documents per cloud query, 20 per client query); the naive version quietly read other patients' plans and truncated at 100 records.
• Ships a dependency-free suite: node tests/regression.test.js runs 11 invariants across three timezones, and each one goes red if the corresponding fix is reverted.
