I build things 🛠️ end to end and keep them maintained. Two directions: ☕ backend / AI application engineering (Java · Spring Boot · RAG · agent tool loops · async pipelines) and 🧰 developer tooling — a family of agent-usage trackers (🧮 aut · 🐾 cbut · 📊 ocut · 🎯 qcut), GNOME Shell extensions and 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 for Java-backend + AI engineering: 🗣️ multi-turn interviews with 🔊 token-level SSE scoring, 📚 a RAG knowledge base (in-memory by default, pgvector optional), 🤖 a controlled agent tool loop and 📨 RabbitMQ state-machine async feedback reports — 🧪 runs end-to-end with no API key in Mock mode |     🔒 private — code available on request |
| 🍜 Local-life-service-platform | 🍜 Dianping-style local-life platform as a 🧩 modular monolith: 🛡️ Redis cache guards, ⚡ a Lua + Redis-Stream seckill with zero oversell and one-order-per-user idempotency, 🔁 a CAS order state machine and 🏪 a merchant console with RBAC — ☕ Java 17 · Spring Boot 3.3 · MySQL 8 · Redis 7 · Vue 3 |    🔒 private — code available on request |
| Project | What it does | Badges |
|---|---|---|
| 🧮 all-usage-trackers | 🧮 Six-tab board over cbut / ocut / qcut: 🔢 cross-tool tokens per model, 🎯 skills and tools side by side, 🕒 one merged timeline, 📈 a card dashboard with window-over-window deltas — ⌨️ a footer that lists only the keys the current tab answers and 🧭 hands the terminal to a tracker's own TUI and back (🚫 no second parser, 🚫 no writes) |    |
| 🐾 codebuddy-usage-tracker | 🐾 Cross-session usage analytics for CodeBuddy Code in an eight-tab TUI — 🧰 tools, 🎯 skills, 🤖 agents, 🧩 plugins, 🔌 MCP calls, 🔢 per-model tokens with 💳 provider credits and 🛰️ agent-span traces, over per-tab 📅 calendar-day windows on a 🔒 metadata-only local SQLite index (🚫🌐 no network) |  |
| 📊 opencode-usage-tracker | 📊 Eight-tab TUI for how you actually use OpenCode — 🧰 tool calls, 🎯 skills, 🤖 subagents with drill-down, 🔌 MCP, 🧩 plugins, 💵 real per-step cost and 🔢 per-model usage totals, a passive read-only log reader over OpenCode's own SQLite (🚫🌐 no network, 🔒 no message bodies) |  |
| 🎯 qoder-cn-usage-tracker | 🎯 Eight-tab TUI for the Qoder CN CLI, modelled on cbut — 🧰 tools, 🎯 skills, 🤖 agents, 🧩 plugins, 🔌 MCP, 🗜️ compaction ledgers, 🔢 tokens next to 💳 credits and per-tab 📅 calendar-day windows; a measured zero stays apart from a route that never reported a token (🚫🌐 no network, 🔒 no message bodies) |  |
| 🧠 AgentOS | 🧠 External evidence & governance layer for a coding agent: 📥 observations → 📊 a verdict → 🚪 a human gate → 📚 promoted memory → 🔁 recall that changes the next prompt (🐍 stdlib-only, 🚫 never edits code) · 🧊 frozen — kept as a record of the attempt | |
❄️ Frozen upstream snapshots, maintained locally — 🚫 no longer tracking upstream. Focus: 🐛 latent crashes, 💧 resource leaks, 🔋 idle power draw and 🧭 GNOME 45→50 adaptation.
| Project | What it does | Badges |
|---|---|---|
| 🔔 notification-grouper | 🔔 Original extension (not a fork) that folds notifications from one app into a single stack — 🪄 zero-config by default, with 4 plain switches if you want them |   |
| 🔥 burn-my-windows | 🔥 Fork of Burn My Windows (frozen at upstream v48): ✨ 26 GPU shader window effects with 🔋 power-aware profiles (AC vs battery), 🎛️ libadwaita live previews and 🌍 34 translations |   |
| 📋 copyous | 📋 Fork of Copyous (frozen at 2.0.1): 🗂️ SQLite clipboard history with 🔎 search, 📌 pins, 🏷️ nine tags and 🕶️ incognito — hardened for correctness, security and leaks |  |
| 🍎 macos-dock | 🍎 Fork of MacOSDock (frozen at upstream v9): 🔍 magnification, 👻 dodge/auto-hide, ⌨️ Super+1…0 keyboard navigation and 🧞 genie minimize/restore — merges MacOSDock + macos-genie |  |
| 🌐 fast-translate | 🌐 Double-copy (Ctrl+C twice) to translate via Google, DeepL, Baidu or Youdao — 📖 a dictionary card for single words, ⌨️ background mode, ⚡ an LRU cache and 🐕 a request watchdog | |

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 Boot · RAG · Agent 工具循环 · 异步流水线） 和 🧰 开发者工具——一整套 agent 用量追踪器（🧮 aut · 🐾 cbut · 📊 ocut · 🎯 qcut）、GNOME Shell 扩展和一些小工具，让我自己的工作流 🔭 可观测、再快一点。
