I recently refactored a front-end web application using React.js, adding new features that enable users to create, edit, and manage music playlists with ease. The app includes an undo/redo feature to facilitate playlist management and a hyperlink for each song, which allows users to directly move, add, remove, edit, and play songs from YouTube without leaving the app.
I created a simple calculator app for Android using Kotlin, which allowed me to gain a foundational understanding of Android app development. Through this project, I learned how to design a user interface and implement basic functionality using the Kotlin programming language.
