Nowadays every second person in the world calls himself a developer. That’s why the owners of the WordPress (WooCommerce) websites, who want to work with highly qualified programmers, should know the difference between the beginner and the professional developer. In this article I will tell you the main differences, which will let you know, if you are working with a beginner in WordPress (WooCommerce) website development, and you should change the developer.

We could have discussed ООP, API and many many other things in this article, but we should stop here.

I realise that this information can seem complicated to a person, who is not a programmer, but it’s really uneasy to distinguish a professional developer from a non-professional. Unfortunately, you can’t be sure that something that can work at first sight, will not bring you any problems in future. But, the more you delve into everything yourself, the quicker you will be able to find someone you need.

The same topic, but from the other hand and in simple language, is disclosed in our article: “Mistakes when hiring and working with developers freelancers”.

I wish you to find the one you will be able to trust all the problems connected with your WordPress website, and not to delve into all the terms and subtleties of website development process.
