Worked on the HWTeng-Teaching/202509-ML-FinTech repository to enhance project onboarding and knowledge transfer by developing a comprehensive README for the 2024_Katie directory. Focused on documentation as the primary technical skill, using Markdown to structure content that introduces team members, outlines FMCG industry background, and details current academic pursuits. Included LinkedIn profiles to improve collaboration clarity and cross-team visibility. No bugs were addressed during this period, as efforts centered on documentation quality and accessibility. The work aimed to reduce onboarding friction and improve project discoverability, with multiple README updates committed to ensure maintainability and ease of use for new contributors.
