Whenever I develop, I also pay big attention to adaptive|responsive web design RWD and web performances WPO, to serve accessible content for each devices, regardless of the bandwidth available. I take care about accessibility to everyone, including search engines SEO.
I came from a software training, and used to work a lot on back-end using PHP (sometimes with the Zend Framework or Symfony), SQL 2 & 3 (MySQL, Postgres, Oracle, SQLite...), and even SolR. I also did some C/C++ & Java (but that was a long time ago).
Now I prefer Node.js and use it even for front-end stuff
(as a server, or mostly to handle commons task for my workflow)
but I know where to use basic Shell to avoid unecessary tools.
I already coded some Ruby or Python scripts, but I've to admit that I am still a noob with these languages. I've even played with ASP, VB, PL/SQL, COBOL and ASMx86 !

Recently, I created with some friends, Putain de Code !, a french community to share high quality posts about development (mainly web), in french.
