I have had the great pleasure of working with Sergey Z on Angular-cli project developing a PWA. Sergey was assigned the task of fixing a project that the previous developers had left in a sad state and where nothing was working. He had the application up and running in no time. After that, he developed several new features. A task in which he excelled. Sergey Z is one of the best developers I have come across on FreeLancer, and I will highly recommend him to you. He is an outstanding developer.

Sergey is knowledgeable and professional. He was consultative and worked through the requirements and scope so that everyone knew what was going to be implemented and why. The code was professional and delivered on time. I would hire Sergey again.
