Welcome, always nice to have more developers here on Steemit. Just a tip, some tags (like the symfony ones you used) aren't used much here yet. You'll reach a broader audience if you post in #programming, and in case you're going to develop Steem-related tools in #steemdev as well :)
Hope you enjoy your time here!
