I really enjoyed working with Sergey. Despite the complexity of the website optimization tasks (WP+Elementor+complex theme+large number of products+multilingualism and multi-currency) - he did everything wonderfully, the site works quickly (both on mobile and PC versions), the server response time has decreased from 1.5 s to 40-113 ms.

I am very satisfied with the result and can confidently recommend Sergey as a responsible and competent specialist. I will definitely reach out to him again!
