Hey there!
I have been looking for an opportunity like that for a long time ago, not really interested in money, just working and practicing with a team, or with others.
I am not a master coder myself, although i think i can handle most of the tasks you could throw at me.
I am programming and developing in most of my spare time, although, i have never worked with ps vita before, only with android and windows applications, however, i dont think it would be that hard to learn with unity's cross-platform design.
Talk to you later, or.. you know.. not :)
Bye!
