The list of programming languages, scripting languages, markup languages, notations and protocols that I have had to deal with as a developer over the years is very large.

As a web developer, I also have appropriate knowledge in the area of full-stack development (PHP, HTML, CSS, JS, etc.), but I would like to distance myself clearly from the specialist area of front-end development or web design.
