Enterprise AI Builder · Java Backend Engineer · Agent / RAG Practitioner
Building practical AI systems for real-world business scenarios.
I'm a Java backend engineer who has gradually moved from traditional enterprise systems into enterprise AI engineering.
Today, most of my work is around turning LLM capabilities into systems that can actually be used inside a company: AI assistants, Agents, RAG, knowledge bases, workflow orchestration, MCP/tool integration, model gateways, observability, permissions and production delivery.
I care less about AI demos and more about one question:
How do we make AI useful, reliable and maintainable in real business workflows?
My current focus includes:
- 🧠 AI Coding — Claude Code, Codex, QwenPaw, DSH, Pi, ChatGPT and coding agents as part of my daily engineering workflow
- 🤖 AI Agents — ReAct, tool calling, MCP, multi-step task execution and agent orchestration
- 📚 RAG & Knowledge Systems — retrieval, reranking, vector databases, enterprise knowledge access and permission-aware retrieval
- 🧩 Dify / LLM Application Platforms — workflow design, model integration, production deployment and platform engineering
- ☕ Java Backend Engineering — Spring Boot, WebFlux, Dubbo, MyBatis, distributed systems and service integration
- 🔎 Search & Data Infrastructure — Elasticsearch / OpenSearch, Milvus, MySQL, Oracle and Redis
- 🐳 Infrastructure & Delivery — Docker, Nginx, Linux, gateways, SSE / streaming and production troubleshooting
I believe the next generation of enterprise software will not simply "add a chatbot".
It will combine:
LLM + Knowledge + Tools + Workflow + Permissions + Observability + Human Collaboration
into systems that can understand intent, retrieve context, call business capabilities and complete real tasks.
That's the direction I'm exploring every day.
AI-first workflow, engineering-driven delivery.
