No certifications are or should be needed. As for new tech, node.js
is very used right now in the market. If you're a javascript
developer and want to learn node.js
, you will have a very easy time. Note that node.js
is commonly used with nosql
databases, such as mongodb
, couchdb
and quite a few more.
If you haven't tried those technologies, it might be a good time to start learning/using/mastering them. Also, I recommend you start using git
if you haven't. You can do wonders with git
.
If you work as a front-end developer once in a while, I extremely urge you to get right on Grunt.js
, since Grunt is extremely useful for a numerous tasks in front end, and it can at some extent, be used for backend, including some php tasks.

I think that's enough for you to get busy for a while. Hope it helps.
