Extremely experienced specialist who knows their craft. I recommend collaboration, clean work, good feedback, excellent brainstorming, and understanding of the client and the project.
Olexiy helped redo the board after the previous developer who disappeared. He completed the work very quickly - in just 3 days, while we had spent several months on it before. Everything was done well and without unnecessary questions. I recommend him for collaboration.
I am very glad that I contacted Alexey. The work was completed in the shortest possible time and with understanding. I recommend for cooperation!
