I want to write a review for all who doubt Constantine's candidacy for the site (in my case for the WP).
I am very pleased to find such an executive as he who did everything right, listened to all my wishes, added points to the TZ that we didn’t talk about and was generally open to explanations and communication.
Such people are rare for freelance, I know it from my own gorgeous experience.
I am glad that I hope I have found a person to realize all my thoughts.

The bone completed everything in time, quickly and affordable, without missing for a few days (who communicated with freelancers - will understand). He fixed all the faults of the design and added what we forgot to take into account at all stages. I understood my blond tongue (“this button to press and this line to wash out”) and I did everything right! He has exhausted TZ without hysterics and khanchism. A huge thanks! I hope we will open up and order a more advanced website and application. Now only you!

Good that there are exceptions and the bone of that confirmation, I was given, corrected the curve site, the prices are most democratic. Thank you very much, Costa. I recommend it!!The !
