Work with functionality in JavaScript

All tasks were completed precisely according to the technical specifications, for some of them I proposed my own solutions, which significantly improved the overall result. Communication is at a high level, always in touch, responds quickly to requests and changes. The project was completed even earlier than the scheduled deadline.
I recommend Kostiantyn for collaboration! If you are looking for a specialist who works qualitatively, responsibly, and "in the know," contact me!

Pleasant client. I recommend for collaboration.
