My name is Francis Schiavo. I'm a software developer specialized in back-end (API and microservices)
My preferred programming languages are: Ruby , NodeJS , Javascript (ECMAScript) and recently go but I also had a good time programming PHP and Object Pascal
Before you ask yourself why didn't he mention HTML and CSS ? Well, that's simple: those are NOT programming languages. They are BASIC markup languages everyone should master at this point in the history of mankind.
