In the Syarify project, I successfully delivered exceptional results while working on the Digital Quran and Prayer Journal features. Overcoming significant challenges: Addressed the issue of extensive storage space usage and network efficiency for audio in the digital Quran feature by introducing a new solution. Users can now choose between downloading all audio or streaming as needed. I also simplified the audio synchronization process, especially for users streaming individually. Implemented local notifications, particularly in the Prayer Journal feature, where notifications needed to be as flexible as possible. I customized schedules to meet these unique requirements, ensuring users on various devices receive notifications according to their schedules.
