I have been a programmer for approximately 8 years. During this period, I had contact with several languages, from C ++ to JS. Throughout this journey, I have been following the PHP language and some of its frameworks such as CodeIgniter and Laravel, which was the one I had the most contact with, for about 6 years in my life.
