Mongodb Realm serverless function http request with oauth

I'm looking for a freelancer to help me setup a serverless function that makes an HTTP request using MongoDB Realm and OAuth authentication. The request should be a GET type and the successful freelancer must include a detailed project proposal in their application. Expertise with OAuth is required.
Previous work or relevant experience is a plus. I need a professional who understands the requirements of this project and can complete it quickly and efficiently.
Thanks for your consideration.
