DO NOT RECOMMEND
We had a rather unpleasant experience of interaction with the company "Grepix". At the project discussion stage, communication was at the highest level, the team seemed very interested and active, but after the first payment our interaction was cut short, we had to wait for each response from a week up to a month. At the same time, they completely ceased to specify the period of product release, began to feed us with promises. If there are some technical problems with the functionality of their product, then the elimination of these problems takes a long time or they do not fix these problems at all. So be sure that after paying for the project you will not receive any technical support. We said during the project discussion stage in advance that we would need technical documentation for the product and they agreed to provide it to us, but by the time the project was completed they said that the technical documentation simply did not exist!
The quality of the product itself is terrible, most likely based on their other projects. The source code is unreadable, making any changes to the project is very difficult, almost impossible, and after them you have to rewrite the code all over again.
We are extremely dissatisfied with the quality of work of this company!
