I build AI tools for developers, and occasionally bend game engines into doing things they were never meant to do.

AI coding agent for Visual Studio 2022/2026 — chat, inline completion, and five autonomous agents that explore, plan, patch, and verify builds.

• 🤖 Five-agent workflow — Ask / Explore / Plan / Edit / Build collaborate via a Handoff protocol
• 🩹 Reliable edits — patch editing, four-tier matching, Healing repair, per-hunk diff confirmation
• 🧩 Extensible — Markdown-based Skills + MCP tool servers
• 🖼️ Multimodal — images, screenshots, PDFs, and OCR reasoning
• 🧠 Long context — 900K token budget with Deep Reasoning
• ✅ Real CI — build, unit tests with coverage, and a hardcoded-CJK string gate

AI mock-interview platform — dual perspective (interviewer / candidate), RAG knowledge base, web search, and voice I/O.

• 🎭 Dual mode — practice as the interviewer, or as the candidate; SSE streaming
• 📚 RAG — LangChain + FAISS retrieval with SHA-256 index integrity verification
• 🎤 Voice — faster-whisper STT + Piper TTS, CPU/GPU selectable, off by default
• 📝 Detailed reports — multi-dimension scoring with per-question evaluation
• 🎓 Tiered — intern / campus / experienced, plus first / second / HR round logic
• 🐳 Four ways to launch — desktop window, scripts, Docker Compose, single container

A pure-Lua HTML/CSS rendering engine that runs inside Genshin Impact's UGC sandbox — zero external dependencies.

• 🎨 HTML/CSS subset — parsing, cascade, specificity, inheritance, :hover / :active
• 📐 Real layout — box model, flex (wrap / grow / shrink), absolute positioning
• ✂️ Shape clipping — circular, rectangular, and arbitrary-shape masks
• 🕹️ Game hooks — onTick(dt) per-frame logic, keyboard + 8 cursor events
• 🦖 Proof of concept — a playable Chrome-style dino runner built on top of it
• 🧪 34 test suites, all passing
