During September 2025, Quynh focused on enhancing onboarding and knowledge transfer for the HWTeng-Teaching/202509-ML-FinTech repository by developing a comprehensive README.md for the 2024_Katie directory. Using Markdown and leveraging strong documentation skills, Quynh structured the README to include detailed introductions, FMCG background, current academic pursuits, and LinkedIn profiles for Katie and team members. This documentation aimed to improve project discoverability, clarify collaboration, and reduce onboarding friction for new contributors. While no bugs were addressed during this period, the work demonstrated depth in documentation quality and accessibility, ensuring maintainability and smoother knowledge sharing within the project team.
