TURNKEY WEBSITE. Part 2/2 - FUNCTIONALITY, API
Unfortunately, my intuition let me down. Once I lost my temper when the performer severely delayed the deadlines for the first part, but he convinced me that it wouldn't happen again..... I curse the day I fell for his tales! I do not recommend working with him on large tasks - Konstantin doesn't care about your deadlines and will keep feeding you nonsense until the end. He solves small tasks right here and now quickly, but this won't help me at all - the project has gone off the rails on all possible deadlines!

TURNKEY WEBSITE. Part 1/2 Layout
Kostyantyn is an excellent performer, knows the subject well, and pays close attention to revisions. There are no complaints about the quality of work. The only reason points were deducted is that the action plan for the project was poorly planned from the start, which significantly impacted the deadlines. However, the problem has been resolved, and we are starting the second part. I can confidently recommend the performer for collaboration!

Removing the link from the Internet resource
It’s great, he’s the one who was able to fulfill the assigned task!I’ve written back somewhere with six freelancers.So no one of them has shaken,refering to the fact that this work can be done only in conjunction with the site administrator or having links in the “organes”)
I put a strong 10th.
P.s. The results of the work are not shared with the public due to its confidentiality (commercial secret)

Connection to the provider’s web services
Constantine was good as a man and a programmer, he did his work great, we explained what we needed in his corner language, and Constantine took the job right away, and made the PHP test file that we tested, and immediately started working together and bringing to the ideal. According to the knowledge of PHP, we set 5, on integration to open card, it is also 5, the most important thing that it understands the process itself and offers the most profitable and best options for implementing the idea, and it is very pleased. We will continue to cooperate with him. Yes, the project was to integrate the supplier’s spare parts base through API services, courageously address with such requests
