Web Developer looking for "unpaid" gig
I am a web developer and i've been developing web apps, backends, frontends and all sort of things for 7 years now. I am looking for some project, not to be paid now but, or to get a small amount on the profits, in case the project get any profit in the future, or a shoutout for myself, that could bring me more freelance or new jobs. Also i am looking for a gig that make me go further than my knowledge right now, something that make me research more, dig more for new technologies or whatever needed to get the job done. If what is needed to get the job done is not in my skill set list, i am looking for to learn and get it done.
Currently my skill set is: PHP (MVC/OO), HTML5, MYSQL, MSSQL, ObjectiveC, JS (jQuery), XMPP, APIs, REST, GIT/SVN and a lot more... Learning/improving: AngularJS, Node.js, Python, RoR, ObjectiveC, NoSQL databases, PHP (as always, forever improving).
Well, any ideas are welcome, i am open to all kind of ideas. Also i am not on the idea of putting my portfolio link here, since this is not a self promotion post, but more of a "Looking for" thingy.
