Packaging on the site (mobile - opencart)
The case when a specialist does not only the assigned task, but looks wider, sensitive and engaged approaches the problem. I recommend it because I just want it to work on our project 🙂
I am looking. Take a bold bet on Sergey, you’ll be happy.

Thank you very much to Sergey for the work done. He is a professional of his business. The task is done almost instantly! So far, a lot of “specialists” couldn’t do it until the end! If you want to solve your task quickly and without any extra problems, I definitely recommend this specialist!

Opencart 2.0 to write a module for the basket. A few upgrades.
I am pleased with cooperation with Sergey. Compulsory, it works quickly, the connection comes out quickly, codes even faster. It is easy to solve tasks from which others have sharked for the lack of skill. I recommend as a professional.
