Unfortunately, no matter how hard I tried to meet the performer, this did not give any result. Initially, the task was to make a calculator for calculating interest, the customer was provided with all the incoming data, formulas and layout of the calculator, after evaluating the incoming data by the performer, he assessed the work as simple and the time to complete it was 24 hours, which generally corresponds to reality. After that, difficulties began - he could not make the calculator calculate a simple percentage, as a result, three days passed and, to simplify his work, I did and provided a FULLY WORKING calculator model in Google spreadsheets, that is, it was required to look and just do the same. However, this did not help either, a few more days passed, the performer rarely got in touch - 5-6 hours after he was contacted. Further, my patience came to an end and I closed the project without execution, after which the performer immediately showed up and as a result of his assurances and convictions, the project was resumed, I agreed to wait "literally a few hours" more. After his next assurance that everything will be done in an hour, more than a day has passed. The project was closed without execution. As a result, a week was spent on an urgent project without any result. I can recommend this contractor only to those customers who have unlimited patience, are ready to constantly explain elementary things and wait 5 hours for answers to their questions.
