During April 2025, Li Yuhsuan focused on improving data integrity for the ocftw/v1.ocf.tw repository by correcting event metadata in the events.yml file. Using strong data management skills and proficiency in YAML, Li addressed inaccuracies in conference names and details for FOSDEM 2023, FOSDEM 2024, and Feira Global Gathering 2023. The work involved a single, well-scoped commit that isolated the patch to metadata without affecting application logic, ensuring low risk to the system. This targeted update enhanced the accuracy of downstream reports and event listings, demonstrating careful change management and attention to data governance within the project.
