# Yaozu Li

**Headline:** Professional profile
**Location:** Antioch, CA, USA

## About

Yaozu Li is an independent Python developer building hands-on projects to deepen experience in backend and AI application development. Yaozu is currently expanding familiarity with API integration, with particular interest in AI-related APIs, while seeking an opportunity to gain experience working on a team. Yaozu’s strongest capabilities are self-directed learning, building systems from first principles, and using systematic experiments to improve technical results. In a personal project, Yaozu built an AI retrieval-augmented generation \(RAG\) system from scratch, including document chunking, storage, and k-nearest-neighbor querying. Yaozu also tested prompt-engineering approaches to reduce hallucinations and evaluated the reliability of AI model responses. Although Yaozu has not yet held a backend internship, Yaozu is direct about that experience gap and is actively addressing it through independent project work and practical experimentation.
