I'll create a MERN stack application that allows users to log in with LinkedIn, fetch their profile data, and create custom resumes using 10 different templates.
For the backend, we'll need to set up:

To deploy this application:
Frontend (Next.js):
Set up environment variables in Vercel:
NEXT_PUBLIC_API_URL: Your backend API URLNEXT_PUBLIC_LINKEDIN_REDIRECT_URI: LinkedIn OAuth redirect URLBackend (Express.js):
Set up environment variables:
MONGODB_URI: Your MongoDB connection stringLINKEDIN_CLIENT_ID: Your LinkedIn app client IDLINKEDIN_CLIENT_SECRET: Your LinkedIn app client secretLINKEDIN_CALLBACK_URL: Your LinkedIn OAuth callback URLJWT_SECRET: Secret for JWT token generationSESSION_SECRET: Secret for session managementFRONTEND_URL: Your frontend application URLMongoDB:
LinkedIn Developer Account:
This implementation provides a complete solution for a resume builder with LinkedIn integration, featuring:
The application uses the MERN stack (MongoDB, Express.js, React.js, Node.js) as requested, with Next.js for the frontend to provide server-side rendering and improved performance.
Please make sure to add the following environment variables to your project:
I'll modify the code to replace the LinkedIn OAuth links with comments so you can fill them in later.
For the backend implementation, here's the updated code with comments instead of actual LinkedIn OAuth links:

For the deployment instructions, here's the updated version with comments:
