Migrate MongoDB to PostgreSQL

I need help with migrating a MongoDB instance to a PostgreSQL instance. This project is for an existing business, not for personal use. I have an existing MongoDB instance and need to create a new PostgreSQL instance. The task requires an experienced software engineer to manage the migration from MongoDB to PostgreSQL. The importance of the successful completion of this project cannot be emphasized enough. Any delay or miscommunication may cause problems for my business operations. I am looking for someone who understands the details of the migration process and who can handle the task efficiently and on-time.

Project will begin with contractor creating schema for new database with solid architecture. This project will last several months as it will take time to migrate. Our backend is in nodejs. We host on Mongot Atlas and will host the new DB on AWS RDS
