Scrolling Class App Development for Course Management

Swipe-n-Learn Tool. We are seeking a skilled developer to create an app focused on managing, adding and updating backend coursework content. Imagine: The front end user of the app selects the course they want to take. When they begin the course, the segments are presented in a scroll fashion, meaning each class segment is a full screen portrait. They can swipe thumb up when the section is completed. Perhaps there is a button they can click on the screen for certain reasons. Each class section is navigated to next with a thump up swipe. This will happen for instance when a video lecture ends, or when they've completed a required task such as a writing exercise, or other assignment. The point is that taking the class feels like scrolling reels on instagram. I want the back end to have drag and drop in content that we add and can arrange in the desired order. Some of the dropped in content will be images, some video, audio, video with audio, and some quizzes or polls. Pauses will sometimes be mandatory, for instance if we determine that say 10 sections of a class should be completed at a time, then the user will be prevented from going ahead. They would be forced to wait until the allowed time that we define, whether that is in hours, minutes or days. Example Class 1 having six parts: intro, lesson, exercise, lesson, final exercise, conclusion. Developer needs to create an easy updateable system that allows class managers to install new classes and modify existing ones.
