Zixuan Wang developed core features for the aigc-apps/PAI-RAG repository, focusing on scalable knowledge base management, multi-modal question answering, and robust evaluation workflows. He architected modular data pipelines and integrated distributed processing using Python and Ray, enabling efficient ingestion and retrieval of both text and image data. Leveraging FastAPI and React, he delivered persistent conversation history, multilingual support, and secure token-based authentication, while refining UI/UX for chat and knowledge base interactions. His work included prompt engineering, LLM integration, and rigorous configuration management, resulting in a stable, extensible platform that supports advanced QA, live web access, and reliable deployment.
