Chat bot
Before closing the project, I quickly checked the code — at first glance, everything seemed fine. However, when I studied it in more detail the next day, it turned out that the code was written extremely poorly, contained errors and meaningless fragments. After that, the contractor completely stopped communicating and ignored all my messages.
In addition, during the work process, he constantly sent messages on Telegram demanding urgent payment, which created additional pressure.
I do not recommend collaboration if you value quality, responsibility, and transparency in work.
