Can I list app and web developer as a extra curricular activity on the common application?

Would developing 20+ apps and making many professional websites (such as social media pages, a music website like Spotify and more) count as an extra curricular activity on the common application? I have a huge passion for computer programming and I am also starting a computer programming club and doing coding competitions. Would all of those go into one extra curricular section, or should I have separate ones like 1. Competitions, 2. Starting a club, and 3. Coding apps and websites?

I would do Coding as one, include that you have made 20+ apps, website, etc and list the competitions if you can fit it. and then have the club be a separate one. whatever you do, though, definitely list this stuff because it’s super cool and impressive
