Convert MYSQL ERD to MongoDB ERD

I am looking for a freelancer to help convert an existing ERD for my MYSQL database to a MongoDB ERD. I already have an existing ERD for the MYSQL database so all that needs to be done is converting it, but I do need help doing it. No data migration is necessary during the process.

When converting Best Practices for MongoDB should be kept as priority to make sure they give best performance for APIs.

There are 30 tables ( 15 tables has less than 5 columns each)
