The task is to build a Profitable website — a revenue-generating website— from the ground up. I want a complete, production-ready solution that includes both the front-end and back-end layers, an ad-friendly layout, and a fully integrated electronic-payment system. Every line of code and all related assets must remain under my ownership, giving me full control over site management, users, and future scaling. Core stack and preferences • Database: MongoDB is a firm requirement. • You are free to choose the language and framework that best pair with MongoDB, provided they are modern, well-supported, and documented. Key deliverables 1. Responsive front-end with clean UX/UI, ad placements, and multilingual support (Arabic + English as a minimum). 2. Robust back-end API with authentication, user roles, and admin dashboard for full site management. 3. Secure electronic-payment gateway integration capable of handling multiple methods. 4. Ads module ready for networks such as Google AdSense (or similar) with easy slot management. 5. Database schema in MongoDB with clear documentation. 6. Deployment scripts or instructions for both staging and production environments. 7. Handover package: source code, database dump, admin credentials, and a brief technical guide. Acceptance criteria • All pages load in under 3 s on a standard 4G connection. • Payment flow passes test transactions without errors and logs correctly in the database. • Admin dashboard updates content, ads, and users in real time. • Codebase includes concise inline comments and a README covering setup and maintenance. Feel free to propose any additional optimizations or monetization features you believe will enhance the Profitable website ’s earning potential.
