How to deal with online certificates? Or will they only play a role on freelance? Ordinary employers do not need them?

Answer 1

You did not specify the main thing - the language.
In enterprise development, certification is generally held in high esteem.
If you use Java, .NET, Silverlight, Oracle, MS SQL - your career path will not do without a bundle of certificates.
If you are a PHP / Python / Node.js / ... developer - employers look at portfolios, experience, test tasks - no one cares about certificates.
In freelancing, no one even cares about the portfolio, first of all, reviews from popular employers are valued.

Answer 2

In fact, certificates are needed not by the employer, but by the programmer, to streamline and consolidate their knowledge.
