This is a pretty broad question; I'm fairly certain I'm proficient in Java (aced the APCS exam, which was by far the easiest AP imo though), and learning Python. I'm in my senior year of high school and programming's what I've wanted to do since the 6th grade. Thoughts on ways to start building up a resumé? (Open source projects? Internships? Do freelance sites such as guru.com allow minors to work?)
Edit: I probably should mention that I am planning to go to college; the current game plan is to have program to help me pay my way through.
