During September 2025, Quynh focused on enhancing onboarding and knowledge transfer for the HWTeng-Teaching/202509-ML-FinTech repository by developing a comprehensive README for the 2024_Katie directory. Using Markdown and documentation best practices, Quynh authored and iteratively updated the README to include detailed introductions, FMCG background, academic pursuits, and LinkedIn profiles for Katie and team members. This work aimed to improve project discoverability, streamline contributor onboarding, and foster cross-team collaboration. While no bugs were addressed, the depth of documentation and attention to accessibility reflect a commitment to maintainability and reducing onboarding friction for future contributors and collaborators.
