List of Atlas / realm experts who can help (paid)

Hello, we’re exploring Atlas and realm to sync several devices and after talking with several companies for consultancy, most of them know MongoDB but almost none of them know realm or Atlas.

I also tried freelancers websites, internet and it’s hard to find people with acknowledge.

What’s the most difficult for us is the roles per files and the correct sync between the whole system.

So, what I’d like in this post is to know which companies or freelancers know very well the product to assist us in some questions and check our project to see if it could be improved.

Thank you in advance
