Which dev platforms can I join so I don’t get stuck with sh**y cheap clients?

Hi all, I’m a full-stack JS developer with 7+ years of experience. I’m thinking of going fully remote and joining a dev platform that can offer me quality clients to work with.

I’m more keen on the curated platforms that would make it easier to reach the top end clients. Long-term projects are preferred over short. I’m based in Brazil so it has to be a platform that hires from Latam region.

What are your recommendations?
