Ask HN: Is there a site to find ppl to work on projects with based on speciality

I'm a back end dev and have a bunch of ideas that I'd like to implement, but my front end skills are really lackluster so am worried that once I do implement the backend code, it's just going to lay there on my computer and never be published. Would like to find a good front end dev looking to collaborate on hobby projects and so thought I'd check here if there was a site that facilitates that. Thanks!
