Jemy Yan — AI Application Engineer

Hello.

I'm Jemy Yan, an AI application engineer based in China. I build intelligent systems powered by LLMs and AI agents — from RAG applications and autonomous agents to Web3 dApps and full-stack AI products. I leverage Claude, GPT, and modern AI development tools to ship end-to-end solutions from architecture to production.

With deep experience in AI integration, prompt engineering, and full-stack development, I turn AI capabilities into real-world applications. I'm passionate about how AI agents and LLMs are transforming software development and creating new possibilities for intelligent automation.

        const greet = () =>
          console.log('Hello,
            World');
        greet(); // we build
            things
        const aiStack = ['LLM APIs', 'Vector DB', 'AI Agents'];
        const devStack = ['Vue.js', 'Node.js', 'Web3'];
        // AI-powered · production-ready
        
      

About

I specialize in building production-grade AI applications — from RAG systems and AI agents to LLM-powered products and intelligent automation. My work spans the full stack: API integration, prompt engineering, vector databases, agent orchestration, and user-facing interfaces. I bring both technical depth and product thinking to turn AI capabilities into reliable, scalable solutions that solve real problems.
