Want to work for free

hi i'm a beginner web developer who is getting things started. I have very little experience and have no completed projects of my own. I'm looking something to work on. AND I NEED NO MONEY. just the experience and knowledge :) here are the things I have practiced so far.

-HTML /CSS /Javascript / Jquery
-Java/Spring
-C

all my skills are very basic and I want to improve them as much as I can working in a project. I need someone who can give me work and review them afterwords. If you are interested please let me know. thanks
