About my work:
Hi. I work with Vue.js since 2017. Before it, I worked with Angular, Backbone, Marionette, jQuery, vanilla JavaScript.
I am a full stack developer, with expertise in Dajngo (since 2015), Django Rest Framework, PHP (since 2008) (Laravel, CPhalcon).
With knownledge in Postrges, MySQL, Firebase, Redis. With projects running Websockets, Celery.
I used Firebase before to achieve to do a real-time chat module in a project with Angular.
Nothing is impossible to do, the limitation is the person behind the code.
