I am looking for a backend developer to create a backend for my existing frontend project, which can be found at https://resumebuilderfront.vercel.app/. The ideal candidate should have experience working with Node.js and MongoDB. Additionally, I need API integration to be included in the backend to ensure the project runs smoothly. Lastly, I would like the backend to have user authentication, so only authorized individuals can access the data.
