Volunteering Oppurtunities

Hi Khan Academy,
I would like to volunteer and help out, I am 13 years old and in Canada. I am wondering if you have any open positions for coding / programming? I have a lot of experience in web development and would like to help out. My reason for doing this is that I want to add on to my resume and improve my extra curriculars. 
I did take a look at the available careers, but didn't seem fit for any of them. for that reason, I questioned here. I solely want to reach out for helping khan academy and for experience.
