I'm a full-stack developer and AI specialist with 2+ years of hands-on experience. I've built production apps with real paying users (Saige Study—an AI tutoring platform) and evaluated thousands of AI-generated code solutions at scale. I'm comfortable across the stack: TypeScript/React frontend, Node.js backend, PostgreSQL, and multi-LLM orchestration (Claude, Gemini). I also have deep experience in code quality assessment, RLHF feedback, and identifying edge cases and hallucinations in AI outputs. I work fast, ship reliably, and understand how to bridge the gap between AI capabilities and actual user needs.
