PROFILE
Jiazhe88
Jiazhe worked on the GAOCheryl/QF5214_2025_G8 repository, developing and refining a multi-model NLP pipeline for financial sentiment, emotion, and intent analysis. Over two months, Jiazhe built the SentimentEmotionAnalyzer, integrating rule-based and FinBERT-based classification with emotion aggregation and intent recognition, using Python and Hugging Face Transformers. The work included optimizing numerical stability, improving performance, and enhancing code maintainability through documentation and refactoring. Jiazhe also introduced labeled datasets for emotion detection and established evaluation tooling, later streamlining the codebase by deprecating legacy components. The engineering demonstrated depth in NLP model integration, data preparation, and maintainable system design.
