A college student from Mainland China.

Undergraduate @ UESTC · Biomedical Engineering (Software Engineering)

AI Agent - Active

• 🤖 Agent Pipeline Engineering — building Function Call toolchains and agent dispatch strategies inside WeChat
• 🎨 Real-time UI Rendering — Markdown rendering engine and chat UI components for AI assistant interfaces
• 🔧 MCP Tooling — learning Model Context Protocol, tool registration, and agentic workflow patterns
• ⚡ Agentic System Design — model scheduling, context management, reactive UI via MCP-driven state

C++17 AI Application Service Platform — self-built HTTP framework, production-grade pipelines

• Self-authored HTTP framework — Reactor model (muduo), state-machine parser, middleware chain, dual-path routing

• Standard MCP Server — JSON-RPC 2.0 tools/list + tools/call, directly connectable to Claude Desktop / Cursor

• Multi-strategy LLM routing — Factory + Strategy pattern, hot-swap between Qwen / Doubao / RAG / MCP

• SSE streaming output — curl callback token-by-token push, zero-wait frontend rendering

• RAG pipeline — Alibaba Bailian knowledge base integration + retrieval-augmented generation

• Async architecture — AI calls offloaded to 8-thread pool, IO threads non-blocking; shared_mutex LRU (500 sessions max)

• ONNX Runtime inference — MobileNetV2 image recognition with OpenCV preprocessing

• RabbitMQ + MySQL — async decoupled message persistence

Lightweight C++ HTTP server framework built from scratch

• Reactor event-driven model with epoll multiplexing
• Stateful HTTP/1.1 request parser + routing engine
• Middleware pipeline, session management, SSL/TLS support

Distributed KV storage with Raft consensus, implemented in C++

• Full Raft leader election + log replication + persistence
• Linearizable reads and fault-tolerant writes across cluster nodes
• Built to understand the engineering gap between theory and production consensus

Notes & practice projects from learning the AI engineering stack

• Covers: Agent architecture, LLM API integration, RAG pipelines, MCP tooling
• Ongoing — updated alongside internship at WeChat AI Agent team
