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. Everything below is bilingual and maintained, not abandoned.
| 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 that records skill / MCP / plugin tool usage into a local 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, 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 upstream snapshots, maintained locally — no longer tracking upstream. Focus: latent crashes, leaks, idle power and GNOME 45→50 adaptation.
| Project | What it does | Badges |
|---|---|---|
| 🔔 notification-grouper | Original extension that groups desktop notifications so a burst arrives as one item |   |
| 🔥 burn-my-windows | Burn / open window effects; a fork of Burn My Windows |   |
| 📋 copyous | Clipboard-history manager; a fork of Copyous |  |
| 🍎 macos-dock | macOS-style dock that merges two upstreams (MacOSDock + macos-genie) |  |
| 🌐 fast-translate | Quick translate popup for selected text; 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。 下面每个项目都是双语文档 + 持续维护，不是废弃的玩具。
