Deploy My MERN Stack Project on Render

I need a proficient developer to set up my fully developed MERN (MongoDB, Express.js, React.js, Node.js) stack project on the Render platform, a free hosting service. The project incorporates numerous essential functionalities, specifically:

- Database integration: The project is connected with MongoDB, which requires careful configuration to ensure seamless operation after deployment.
- Authentication: There are built-in user authentication features which need to be properly set up and tested post-deployment.
- API endpoints: The project contains multiple API endpoints that need to be verified for functionality and accessibility once live.

The ideal candidate for this project should have:
- Extensive experience with MERN stack and its components.
- Proficient knowledge of MongoDB and its integration with MERN.
- Prior experience with deploying projects on Render.
- Familiarity with setting up and testing authentication features post-deployment.
- Understanding of API endpoint functionality and accessibility verification.

Please provide examples of previous MERN projects you have deployed, specifically those using Render and MongoDB.
