Leyan Zhang developed and enhanced data processing pipelines for the GAOCheryl/QF5214_2025_G8 repository, focusing on onboarding, NLP capabilities, and robust data governance. Over two months, Leyan refactored and stabilized local, live, and batch workflows using Python, Pandas, and SQL, improving data aggregation, file management, and error handling. The work included upgrading NLP modules, consolidating code to reduce technical debt, and reorganizing data paths for Nasdaq datasets to streamline storage and access. By establishing project scaffolding and comprehensive documentation, Leyan enabled faster feature delivery and maintainability, demonstrating depth in data engineering, natural language processing, and workflow optimization.

Mar 1, 2025In March 2025, delivered a foundation and a series of enhancements for GAOCheryl/QF5214_2025_G8, strengthening onboarding, NLP capabilities, data processing accuracy, and code maintainability. Established project scaffolding and comprehensive documentation to accelerate collaboration. Upgraded NLP modules to v4 and v7 with refactoring into stable local/live processing paths. Improved data aggregation logic and cleaned up the core pipeline for reliability. Refactored and renamed key modules to reduce debt (aggregate_v1.py -> aggregate.py; nlp_v7.py -> process_local.py; nlp_live_processing.py -> process_live.py). Hardened SQL read/upload workflow and removed legacy TeamTwo modules to reduce fragility and technical debt. These changes collectively boost processing throughput, data quality, and long-term maintainability, enabling faster feature delivery and clearer roadmap planning.
