I've built upon my wordpress skills mainly outside of my placement/university. I started a blog in wordpress at the beginning of my placement, however now my entire site is using wordpress, along with any micro sites or test sites I do.
I've used multiple version control systems in the past, during my time at uni we focussed mainly on tortoise SVN, and during my placement I've been using git. I also have a GitHub account for small projects I do outside of work/uni.
I've created a few basic phone apps; a couple of android ones that were for university assignments, along with some practise ones across multiple platforms using an application called phone gap.
