* Requirements:

* APIs for creating, updating, and listing plans and subscriptions.

* Database schema for plans and user subscriptions.

* Integration with a payment gateway for secure transactions.

* Logic for subscription renewals, cancellations, and access control.

* Manage relationships between clients and providers, including subscription-based access.

* Requirements:

* APIs for searching providers with filters and pagination.

* Database schema for provider profiles and client-provider relationships.

* Allow clients to access assigned content based on subscriptions.

* Requirements:

* APIs for creating, updating, and retrieving content.

* Database schema for content and assignments.

* Logic for scheduling and access control.

5. Social Engagement

* Support real-time user-generated content (e.g., posts, temporary stories) viewable by followers.

* Requirements:

* APIs for creating, listing, and deleting posts/stories.

* Database schema for content (text, images, timestamps) and expiry logic for stories.

* Real-time updates via WebSockets or server-sent events.

* Caching (e.g., Redis) for feed performance.

6. Third-Party Directory Integration

* Manage a directory of external entities (e.g., businesses) with details like name, type, and hours.

* Support interaction with entities (e.g., via phone or messaging apps).

* Requirements:

* APIs for listing and retrieving entity data.

* Database schema for entities and related data (e.g., items, pending implementation).

* Admin Panel APIs for managing entity data.

* Integration with external communication APIs (e.g., WhatsApp, phone links).

7. Push Notifications

* Deliver timely updates (e.g., new content, messages, reminders) to users.

* Requirements:

* APIs for sending and listing notifications.

* Integration with push notification services (e.g., Firebase Cloud Messaging, OneSignal).

* Database schema for notification logs.

* Queue system (e.g., RabbitMQ) for scalable delivery.

8. Cloud-Based Image Management

* Handle secure uploading and retrieval of user and provider images, as well as content-related visuals.

* Requirements:

* APIs for image upload and retrieval.

* Integration with cloud storage (e.g., AWS S3, Google Cloud Storage).

* Image processing (e.g., resizing, compression) for performance.

* Database schema for image metadata.

9. Payment Gateway Integration

* Enable secure transactions for subscriptions and other purchases.

* Requirements:

* APIs for payment processing and webhooks.

* Integration with a client-approved payment gateway.

* Database schema for transaction records.

* Logic for renewals and cancellations.

10. Admin Panel Integration

* Provide a backend interface for managing content, notifications, and analytics.

* Requirements:

* APIs for admin actions (e.g., managing entities, sending notifications).

* Database schema for admin data and logs.

* Role-based access for admin users.

* Analytics endpoints for user engagement and subscription metrics.

11. Messaging System

* Enable communication between clients and their subscribed providers.

* Requirements:

* APIs for sending and listing messages.

* Database schema for messages (sender, receiver, content, timestamp).

* Real-time messaging via WebSockets or similar.

* Logic to restrict messaging to subscribed relationships.

12. Multi-Language Support

* Support multiple languages (e.g., English, Arabic) for UI and user inputs.

* Requirements:

* APIs for language-specific data.

* Database schema for localized content.

* Logic for handling localized user inputs.

Technical Requirements

* Preferred Stack (Rebuild):

* API Framework: Node.js/Express or Django (REST or GraphQL).

* Caching: Redis for real-time feeds and notifications.

* Cloud Storage: Google Cloud Storage.

* Scalability: Design to support 10,000+ users (database indexing, caching, load balancing).

* Monitoring: Implement logging (e.g., AWS CloudWatch) and error tracking (e.g., Sentry).

* Security: HTTPS, JWT, OAuth2, data encryption, GDPR/PCI compliance.

Deliverables

* Fully functional backend APIs supporting all listed features.

* Database schema optimized for performance and scalability.

* Admin Panel backend for content and notification management.

* Documentation for APIs, database schema, and deployment.
