🎯 Focus: AI Native Full-Stack Products & Production Engineering

• Independent R&D: Focused on building production-grade AI Native full-stack products, exploring the boundaries of edge inference, civic governance intelligence, and multimodal human-computer interaction.

• Key Milestones: Independently architected and launched 4 AI Native products from 0 to 1; led a team in the Shunde AI Hackathon and won 2nd Place in the Enterprise Track.

🚀 Agent Platform: LangGraph App (ai.firetable.tech)

• Dual-Graph Agent Workspace: Built on LangGraph with two parallel compiled graphs ("foreground streaming chat graph + background async summarization graph"), unifying multi-agent collaboration, tool calling, memory, and RAG.

• 3-Tier Cascading Intent Router: Short-circuits from "structural rules → regex/lexicon matching → LLM structured fallback" to dispatch domain sub-agents (Code / Crypto / Research / Chat), minimizing TTFT and token cost.

• Cross-Thread Memory & Observability: Persists long-term user facts via RFC 6902 JSON Patch alongside K-turn window auto-summarization; captures nested LLM / Tool / Node spans in Postgres with per-turn latency waterfalls.

• 3-Way Hybrid RAG & Eval Studio: Ingests 7 document formats (with Vision OCR) using pgvector 3-way RRF (Keyword + Vector + Tag) hybrid search and Cohere / Jina semantic reranking; features rolling credit quotas and an LLM-as-a-Judge Evaluation Studio.

✨ Digital Human: 3D Anime AI Companion · XiaoChun (xiaochun.firetable.tech)

• Client-Side 3D Virtual Human: Inspired by Grok Ani, breaking beyond rigid Live2D animations and pre-rendered lip-sync videos; built on a zero-backend browser-native architecture integrating SenseVoice ASR, WebGPU (WebLLM) reasoning, Edge-TTS speech, and EMAGE (WASM + ONNX INT8) full-body gesture generation across parallel Web Workers with 100% local data privacy.

• Custom Skeletal Motion Blending Pipeline: Unified scheduler orchestrating breathing, thinking, co-speech gestures, and turning footsteps across 52 bones with FootIK ground locking and gaze tracking—eliminating multi-source jitter and T-pose flashbacks while supporting VRM 1.0 / 0.x.

• Model Pruning & Delta Outfit System: Quantized and pruned EMAGE (model size 504 MB → 71.6 MB, per-step inference latency halved to 79 ms) and shrank initial bundle size from 6.95 MB to 1.01 MB; pioneered base + vrmaddon delta outfit loading, cutting download traffic across 9 outfits by 65%.

• Cross-Platform Desktop Pet & 1-Line SDK: Runs instantly in Web browsers or as a transparent Tauri desktop pet (macOS / Win / Linux with auto-updater); published @firetable/project-xiaochun SDK enabling 1-line script embedding into any webpage.

🏆 Hackathon: CivicRadar · Shunde AI Hackathon (12345.firetable.tech)

• Hackathon Achievement: Led the team to win 2nd Place in the Enterprise Track out of 35 competing teams; spearheaded the V2 industrial-grade refactoring post-competition, abstracting four @civic/* core packages and processing 128k Shunde + 96k Guangzhou Tianhe real-world civic tickets.

• Brain-Inspired "System-1 / System-2" Architecture: Engineered a System-1 client/edge 4-Head ONNX neural classifier (only 4.5 MB, 0.079 ms latency, 12,600+ TPS, 99.86% critical-risk recall with zero false negatives), offloading 80%+ compute before invoking the System-2 local 27B reasoning model for CoT-stripped structured JSON extraction.

• "Fake-Closure" Radar & Spatio-Temporal Clustering: Invented a 7-day post-resolution temporal risk radar to automatically flag superficial closures and repeat complaints for escalation; combined BGE-M3 embeddings with Tianditu CGCS2000 zero-drift coordinates to reduce cross-address false clustering from 14.2% to 0.0%, generating official dispatch drafts.

• Microsecond Reversible Desensitization & 30s Onboarding: Built a national-standard checksum PII state machine (13 μs/ticket, outbound air-gap isolation + 100% lossless in-memory restoration); paired PostgreSQL Schema physical multi-tenancy with AI Scout to onboard any new city's statutory whitelist and 5,600+ self-learning aliases in 30 seconds zero-code, natively exposed via MCP.

🎮 Indie Game: The 11th Forest (forest.firetable.tech)

• AI-Driven Game Engineering: Built on Phaser 4 + React 19 and shipped from 0 to launch in 7 days using standardized prompt pipelines for sprites (Nano Banana 2 + automated matting scripts), BGM (MiniMax), and voiceovers (ElevenLabs).

• AI-Friendly Data-Driven Engine: All levels, monsters, weapons, and characters are declaratively defined via YAML + Zod Schema, allowing new content injection without touching engine code—naturally tailored for AI batch generation.

• In-Browser Visual Level Editor: Zero-backend web editor powered by a custom Vite plugin for direct local YAML disk read/write, supporting collision-wall drawing, spawn placement, and sprite slicing.
