Worked on enhancing the Persian calendar UI by developing a calendar swipe interaction feature in the persian-calendar/persian-calendar repository. Focused on implementing threshold-based swipe detection using Kotlin to improve interaction reliability and reduce accidental user actions. Addressed a usability issue where non-touchable items appeared below the day view, refining touch target accuracy and overall user experience. Applied robust UI/UX design principles throughout the process, ensuring that event consumption only occurred after the threshold check. This approach strengthened the reliability of calendar interactions across devices, contributing to a smoother mobile development workflow and reducing potential support issues related to user input.
