CS undergrad · building ☕ Java backend & 🤖 AI applications, maintaining 🪞 GNOME Shell extensions, and writing 🧰 small dev tools.
English · 简体中文
I build things end to end and keep them maintained. Two directions: backend / AI application engineering (Java, Spring, RAG, agents) and developer tooling — trackers, extensions and small utilities that make my own daily workflow observable and a little faster.
| Project | What it does | Badges |
|---|---|---|
| 🎤 AI-Interview-Practice-and-Feedback-System | AI mock-interview copilot: multi-turn interviews, a RAG knowledge base, an agent tool loop, SSE streaming and RabbitMQ async report generation |     🔒 private — code available on request |
| 🍜 Local-life-service-platform | Dianping-style local-life platform: Redis cache guards, a Lua + Stream seckill with zero oversell, and a merchant console with RBAC |    🔒 private — code available on request |
| Project | What it does | Badges |
|---|---|---|
| 📊 opencode-usage-tracker | OpenCode plugin + TUI for skill / MCP / plugin tool usage — live via plugin hooks, or synced from OpenCode's own SQLite database (no network, no message bodies) |     |
| 🐾 codebuddy-usage-tracker | Eight-tab TUI that shows how you actually use CodeBuddy — every tool, skill, agent, plugin and MCP call, plus per-model tokens, indexed from local logs (no network, no message bodies) | |
| 🧠 AgentOS | External evidence and governance layer for coding agents: observations → verdict → human gate → durable memory (zero third-party deps, never edits code) · 🧊 frozen, kept as a record | |
❄️ Frozen upstream snapshots, maintained locally — no longer tracking upstream. Focus: latent crashes, leaks, idle power and GNOME 45→50 adaptation.

|---|---|---|
| 🔔 notification-grouper | Original extension that folds notifications from the same app into one stack — zero-config |   |
| 🔥 burn-my-windows | 26 GPU shader window effects with power-aware profiles; a fork of Burn My Windows |   |
| 📋 copyous | Clipboard-history manager with search, tags and incognito; a fork of Copyous |  |
| 🍎 macos-dock | macOS-style dock with magnification, dodge and genie minimize; merges MacOSDock + macos-genie |  |
| 🌐 fast-translate | Double-copy to translate selected text via Google, DeepL, Baidu or Youdao; a fork of translate-assistant | |
我喜欢把东西从零做到能用，并且持续维护。两条主线：后端 / AI 应用工程（Java、Spring、RAG、Agent） 和开发者工具——用量追踪器、扩展和一些小工具，让我自己的工作流可观测、再快一点。

|---|---|---|
| 📊 opencode-usage-tracker | OpenCode 插件 + TUI，记录 skill / MCP / 插件工具的使用——实时靠插件 hook，或被动同步 OpenCode 自己的 SQLite 数据库（无网络、不记正文） | |
| 🐾 codebuddy-usage-tracker | 八 Tab TUI，一眼看清你如何用 CodeBuddy：工具、skill、agent、插件、MCP 全记录，外加每模型 token，索引自本地日志（无网络、不记正文） | |
| 🧠 AgentOS | 给写码 Agent 的外部证据与治理层：观察 → verdict → 人工确认 → 长效记忆（零第三方依赖，绝不改代码）· 🧊 已冻结，作为一次尝试的记录保留 | |
❄️ 冻结上游快照，本地独立维护，不再跟随上游。主做潜在崩溃、资源泄漏、待机功耗 + GNOME 45→50 适配。
