During December 2025, Onestone Yang enhanced user experience and accessibility across two repositories by addressing documentation and localization challenges. In apache/datafusion-comet, Yang corrected a broken README link using Markdown, ensuring users could reliably access the correct project overview. For potiuk/airflow, Yang expanded Korean UI localization by adding missing translations in JSON, improving consistency and usability for Korean-speaking users. The work demonstrated strong skills in front end development, i18n, and link management, with clear, well-documented commits that supported cross-team collaboration. These targeted improvements reduced onboarding friction and support queries, reflecting thoughtful attention to both technical detail and user impact.
