Work on the educational-methodic aid project was complicated but interesting, there was a very large amount of information that was to be processed and then added to the aid, which was also very large. The difficulty was also that there was little information in open access on this topic. The subject of the aid was very interesting to me. It was pleasant to communicate and work with Ruslan.
The topic is new to me, but it seemed very interesting. From the Customer - clear TZ, constant connection, which contributed to the quick performance of the task. Payment is made in time and in full amount. Thank you for cooperation!
