First of all: kudos on building this app. I think it's really impressive to build and showcase your project at such a young age.

I'm actually a user of https://wip.co/ . I think it's quite similar to your project. You should check it out. Also, check out https://peerlist.io/

Social platforms/marketplaces are genuinely difficult, cause it only works if you have enough users (both, demand and supply).

Since it's your early projects (I'm assuming), I think you should built it purely for the sake of learning and feedback. Even if it doesn't work out, the experince is extremely valuable.

Later - if you are serious about a sustainable project - I would recommend that you study your alternatives/competitors (such as the ones I just shared), and figure out what works for them and what are their users missing.
