We were doing only part of this site. Ore work was dedicated to creation of the tool for remote teaching.
Tutors can manage their schedule and students. Students can assign lessons to the tutors they need. When time comes both tutor and studend are being notified by emails and online lesson session begins. Tutor and student can chat with each other and use whiteboard to draw pictures, math formulas etc.
Both of them can leave feedbacks about the lesson.
