Worked on the syncfusion/maui-toolkit repository to deliver enhancements focused on user interface and data visualization for MAUI applications. Developed new features for the Date/Time Picker, introducing additional date formats and active view selection to improve input flexibility and user experience. Added a trackball feature to the Spark Chart component, enabling more interactive data exploration within the app. The work involved end-to-end feature delivery using C#, XAML, and UI/UX design principles, culminating in the release of version 1.0.10. The contributions addressed both usability and interactivity, reflecting a focus on front end development and data visualization improvements.
