I am an experienced Full Stack Developer, during the decade of my career, I saw the technology change at incredible speed, making me learn a new stack every year.
I started working during the time when iframe and tables were "cool", and PHP was "the language of the future". I adopted Node.js in the moment that I saw that was superior to PHP and I never regretted that, from that day every project I develop, was with Node.js.
During that time, not only my choice of database transitioned from MySQL (major choice in PHP) to MongoDB and finally to Postgres, redis and Mongo (choosing the right one for the right project), but I also learned that a successful website doesn't use simple queries, but also need that the database needs to execute some code on its side (triggers, functions, ...).
I also made big jumps on the front end. Starting with vanillajs (badly), move to jQuery, then Kendo, then Dojo (a light version of jQuery), moving back to vanillajs because those frameworks had terrible performance, and finally discovering the joy of the uber-complicated first version of Angular. At the end, I discover React, and that has become a big part of my stack.
I've been always passionate about my job, and I really enjoy what I do and learn new things. Many of the things that I learned during these years I didn't mention here, just because aren't relevant, or because the description will be too long.
(At some point during all of that I also discover TDD and Docker)
