Reviews

Igor Mezakov is a professional performer who demonstrates high-quality work, efficiency, and deep technical competence. Most reviews highlight his ability to quickly and effectively solve complex tasks, including parsing, API development, database management, and frontend work. He often exceeds expectations, works with understanding, considers client wishes, offers alternative solutions, and remains in communication at all stages.

However, there is one negative review: client Alexey Klimisha pointed out rudeness, lack of client orientation, and incompleteness of the website. Igor Mezakov explained the situation by stating that the client unjustifiably increased the scope of work and did not pay for the completed tasks (including a complex system with parsers, API, frontend, and database), while part of the functionality was implemented and accessible via a link. He also warned about the risks of collaboration without a clear technical specification and secure transaction.

Summary Review:
A professional and experienced specialist who completes complex tasks quickly and efficiently. In most cases, he is a reliable and communicative performer. However, there is a risk of conflict in the absence of a clear technical specification, contract, or secure transaction, as well as in cases of non-payment for completed work.
