I am a Senior Java and AI Agent Development Engineer with more than nine years of experience building backend systems, microservices, SaaS platforms, and enterprise AI applications. My background spans international logistics, enterprise learning, passenger transportation, and B2B e-commerce.
I specialize in Java ecosystem development, including Spring Boot, Spring Cloud Alibaba, MyBatis, Redis, MySQL, MongoDB, RocketMQ, and distributed-system design. I have delivered core business modules, API platforms, data integration services, high-concurrency optimizations, and reliable asynchronous processing workflows.
I have recently focused on enterprise AI platforms and agent engineering. I design RAG systems, multi-agent workflows, LangGraph orchestration, ReAct and Plan-Execute-Critique patterns, vector retrieval pipelines, prompt chains, and streaming LLM applications.
I have practical experience developing knowledge-base question-answering products with document ingestion, multimodal parsing, hybrid dense and sparse retrieval, re-ranking, metadata filtering, query rewriting, and SSE streaming responses. My work has improved retrieval recall and enabled structured, scalable AI capabilities for enterprise products.
I value maintainable architecture and use design patterns such as strategy, factory, builder, template method, and state machines to build extensible systems. I am also experienced in performance troubleshooting, concurrent programming, JVM analysis, production issue resolution, and technical leadership for module delivery and junior mentoring.
