    “I will highly recommend Sergey to you. He has helped us with a complex Angular-cli application that had stopped working and where a lot the unit tests no longer worked. Our own developers had given up. Within a few days, Sergey had fixed all outstanding issues. We decided to expand our engagement with him and got him develop a couple of new modules. The quality of code we received back is of a much higher quality that we have seen before on freelancer. We will definitely use him in future.”
