I was responsible for building various parts of the user experience, including multimedia file selection and upload, image and video preview, scrollable thumbnails, content playback within profiles, and various interactive interface controls.I also worked on organizing and evolving the application's architecture, aiming for maintainable, scalable code prepared for future feature additions. Vyra's goal is to become a complete social platform with user profiles, multimedia posts, content discovery, and user interaction.This project allowed me to gain practical experience in mobile programming, interface design, multimedia content integration, bug fixing, and continuous feature improvement.
