Hello everyone. I am a computer science and applied math double major. I want to get involved in an open source project so I can gain experience and so I have something to show potential employers that I worked on. I just created a GITHUB account and I am not an expert at using it, nor have I contributed to a project before, but I am pretty good at Java. Are there any good open source projects I can work on to gain experience. where I don't necessarily need to be an expert?
