Yifei Yin

During July 2025, Yifei Yin focused on stabilizing the user experience and visual consistency for the toeverything/AFFiNE repository. Yifei addressed two critical bugs, enhancing both the accuracy of calendar event times and the uniformity of embed block theming. By leveraging JavaScript and TypeScript for timezone-aware date formatting, Yifei ensured that event times display correctly in each user’s local timezone. Additionally, Yifei improved CSS integration by replacing hardcoded variables with a more flexible theming approach, resolving visual discrepancies across embeds. This work demonstrated depth in frontend development, particularly in date and time handling, theming, and cross-timezone reliability.
