I regret not reading the reviews before the start of the collaboration, immediately registered, added the project and immediately wrote by Alexander Keshman. I liked his conditions of cooperation that he will do the laboratory in one day and I agreed, before placing the amount in the seafood, I asked him if everything was clear, if there were no questions ? He answered that there was no, and I put the amount into the seafood. After eight hours in the evening comes the question about the performance of the work. Conclusion: a person does not look at what tasks he takes before the beginning of the cooperation that he can perform. I also want to add that Alexander Cashman does not invest in the deadline. As for tasks, they are done incorrectly, even after a few corrections. The graduate does not do any tests of the program before sending.
I also add screenshots of the program tests.
I don’t recommend the counterfeit.

The work is not done! From the beginning there were clear requirements for the deadlines of execution with the impossibility of continuation. Even after the extension of the deadline of the work I did not get. Unfortunately, there are no intermediate options or final options yet. The work itself has lost relevance, I don't see any sense to continue this project with this execution. I want to note that it’s not the first time I’m going to Alexandra, and before all the work was done successfully and timely, why it happened this time, I don’t know.

20.04.2021 we concluded the project and started working with Alexander.Created a chat in the telegram channel, I, my work partner and Alexander.She put 7,000 rupees in the seafood, the deadline of the work was 22 days.Within this time, we set up and found potential customers to buy a new program.The first time we called, Alexander had opened 3 projects, he said he would do them in 2-3 days and start working on my project.I wrote him messages, he said it was ok, but the intermediate results of the work did not be sent.On the 26th of January, the plague began.Alexandra had no questions, but there was a lot of answers in the work.He did not work with me, he did 10 more.He has all these good reviews.Where are these feedback from?Are they ordered?Did he “do” the program for himself?He did not respond to the messages, and when he responded he wrote that he was delayed, no electricity worked, personal reasons and bla bla and constantly asked to carry the deadlines.I hoped he would do something and the deadlines were transferred, from 02.05 to 7, then to 15, to 21, to 24.Then some movement began.I and my partner had questions about the program, a lot of shortcomings, etc.He didn’t send intermediate results, of course we couldn’t all look quickly, add corrections and again succeed in time.Alexander asked for a delay again.The result was extended again to 27.05.21
28.05.21 at the evening, he sent the installation file of the program and wrote, "Hello.There are some failures and errors in the program.But in general, what is left is little compared to what was done.I will be in touch from Monday.”

It is placed in front of the fact, even without knowing the program has been opened, does the program work?As a result, the program opened only on one computer, the instructions file was not opened at all, my partner couldn’t open the program.The whole program is curved.I asked him, “Do you leave us until Monday by default?Nothing is done again?Although all the deadlines have passed and we are very pleased to put you in time and you have promised several times.The program is not awarded, how do you understand?”

That man has delayed our project.On 10 projects, I think he earned money and we lost money.Who will replace them now?His answer was: “Hello.By the deadlines clearly my calculation, but on the other hand, let’s look at the pattern that you sent from the beginning and how the program looks now, the improvement of the user interface also took not a little time.The original task remains to carry out the report and translations.I saw, you re-published this project, if you intend to complete the project, then on Tuesday I am ready to do it.”
Again the silence.He did not respond to the messages.The date of submission of the project is closed, the executive has not contacted, the program has not been sent.A minute ago I opened an arbitration and the man immediately woke up and wrote...

A short summary:
He did not send reports of work, did not ask any questions, and only asked for a permanent delay.When he sent his “work” it turned out not at all what was initially thought. He did not send what was obtained in the program and I could not send corrections. The program is crooked, not beautiful, a huge number of shortcomings.

You can’t call the programmer, the calls are blocked, he understood the information that I wrote in the TOR in his own way. Due to the fact that he did not send brief reports of his work, I could not tell where what went wrong. As a result, when the program was already supposed to be finished, there were a lot of shortcomings, the programmer again asked for time to fix them. If he had sent brief reports, this would not have happened. I created a telegram chat with my partner for the convenience of communication, Alexander did not answer some messages, why he missed the deadlines - he did not answer. He promised to make the program until a certain time, at that time he did not send anything and did not answer messages. When I got in touch, the next excuses began why something could not be done.

When my partner wanted to communicate with him by voice, he asked in response, “Shall I also send the program with my voice?”
As a result, the program is NOT done, what is done is not opened properly, no data can be entered, the program closes immediately, i.e. it needs to be completed or redone (we do not have source files), we missed all the deadlines for releasing the program to the market, we lost customers who have been waiting for this program and have to look for a new programmer.

Who will make up for this loss of time, money and customers?

Such a "programmer" needs to lower his rating or even block him on this site and fine him for such an attitude towards customers. Not an employee, but a scammer

The executor is easy to get in touch, with the technical task dealt with, responsive and executive. In general, the performance of the executive is positive, but the requirements have not been fully fulfilled within the specified time. Also, the executor did not follow strictly and had to repeatedly indicate these differences, but the executor corrected everything reversively, although this was in detriment of the conditional time of execution.
