I know this is a weird question and I dont know if Im allowed to ask this here or not, if not feel free to delete this post. But is there a feature on this site or some other site where Im able to post my project Im working on so other people could use it and together try to improve it?
Thanks in advance!
What you are looking for is probably is Open Source community. The best way to achieve that is using something like Github, where you can make your project available as a repository and share for other people to contribute.

Anyways, I suggest you upload your project to Github if you’re thinking about making it public, that is one of the best ways to show your projects on job interviews or as a portfolio.
