    The following tasks were assigned:
    Develop a "Support Service" where clients can contact "Support" agents at specified times from 8:00 to 00:00 - The bot automatically determines the time and blocks functions. When a client writes during working hours, the ticket goes to all available operators in personal messages.

All comments and wishes were corrected quickly, without any additional words. Despite the fact that a little exceeded the fixed deadlines, it was justified, as the tasks were really difficult. This does not affect the quality of the final product. I look forward to further cooperation with Nazar and definitely recommend him as a reliable execution for developing technically complex projects.

He also loyally attended additional functions and rectangles that were not included in the TZ, for which he was grateful! He even agreed to a Google Meet meeting to explain to me how everything works. Overall, the impressions from the work remained positive. I will go to him again! Thank you !
