Ask HN: Is there a platform for finding programer colleague?

I‘m searching for a plaform that allows me

- to submit ideas I have

- let others vote, comment and join the project

- once it seems to have enough positive feedback and programmes (people that joined the project) change the status to in development

- once done change the status to done.

Does such a plattform exist? If not, how you would search for it (google keywords)?
