Our customer is engaged in the field of education and has a digital educational platform for personalized training (courses) in the academic disciplines of the aviation industry: aerodynamics, aircraft and their functional systems, the device of aircraft engines, etc. It is a web-based system that manages the learning process and supports a variety of forms of educational content developed by our customer in conjunction with his partners. It was necessary to increase the productivity of learning, simplify the perception of teaching materials, and as a result, improve the quality of education. The whole process was divided into three stages. At the first stage, we improved the training materials, at the second stage, we were engaged in their integration with the existing web system, and at the third stage tested the entire system.
