~$cat summary.md

I am a Web Developer with over 3 years of hands-on experience building high-performance web applications and integrating practical AI solutions into production. My core strengths lie in scalable frontend architecture, UI rendering optimization, and conversational AI (RAG pipelines, smart chatbots, SSE streaming, prompt tuning). I always focus on turning complex technical logic and business workflows into smooth, intuitive user interfaces that solve real-world problems.
