MERN Stack Educational Marketplace Development

I'm looking to build an educational marketplace that allows users to upload their own educational material and potentially earn from it. The platform should also provide a subscription payment option and allow users to set which files are free for download. A key aspect of this project is the secure handling of payments and user data, as well as ensuring a seamless user experience.

Key Features:
- Users can upload and sell their educational materials
- Subscription payment functionality
- Customizable download options for users
- Credit cards, PayPal, and Stripe payment methods
- Robust user authentication via email and password and social media login integration
- Efficient and user-friendly categorization system for educational materials (e.g., subject-based, grade-based, topic-based)

Ideal Skills and Experience:
- Proficient in MERN stack development (MongoDB, Express.js, React, Node.js)
- Experience in building marketplaces or e-commerce platforms
- Payment gateway integration (particularly with Credit cards, PayPal, and Stripe)
- Strong understanding of user authentication and data security
- Prior experience in building subscription-based models
- Knowledge of creating and managing file upload/download functionality
- Familiarity with educational content categorization and structuring

The end goal is to create a comprehensive, user-friendly, and secure platform that enables creators to share their educational material and users to access a wide range of resources easily.
