Olx парсер в базу даних
Constantine is a decent and responsible person.
But this order turned out to be too complicated and specific.
Unfortunately, the developer did not deal with it.
About all the nuances I told immediately and we tried to find a solution, always was in contact
He was carefully trying to fulfill the task.
With the agreement of both sides, the order was cancelled.

Парсер OLX
Очень классный, терпеливый и отзывчивый специалист. Проект по своей особенности оказался очень специфическим и своеобразным.
Константин, уделил сверх внимания проекту, особенно правкам которых было предостаточно. И особенно не отказывал по консультациям которых было уйма.
Я результатом очень довольна и вниманием Константина к проекту. Рекомендую на 100%
