I gave Denis the highest marks because in the end I received a quality product. During the tests, I did not find any bugs. But I ask you to pay attention that if it is critically important for you to meet the stated deadline, then you may not succeed, because in my case I waited about 3-4 weeks longer than Denis stated. Various factors that are currently in Ukraine may have influenced this. This could also be the case. Since this deadline was not critical for me, I waited and therefore gave the highest mark. Overall, I liked the collaboration, but there may have been a lack of feedback when deadlines were not met, regarding what was happening.
