🌟 Project Overview

My Financial Trading (MFT) is a comprehensive web application built to deliver high-quality financial trading education. It bridges the gap between expert knowledge and eager learners through a secure, interactive, and scalable platform.

The system is designed with a microservices-inspired architecture, separating the high-performance Next.js frontend from the robust Node.js/Express backend. It serves three distinct user roles—Students, Admins, and Super Admins—each with tailored dashboards and functionalities.

Key highlights include a custom-built secure video streaming engine, a real-time community feed akin to social media, and a complex payment infrastructure supporting fiat and cryptocurrencies.

✨ Key Features

🎓 Advanced Learning Management

• Structured Course/Sub-course System: Hierarchical content organization for streamlined learning paths.

• Secure Video Streaming: Custom HLS (HTTP Live Streaming) implementation with signed tokens and time-limited access to prevent unauthorized downloads or sharing.

• Progress Tracking: Granular tracking of video completion and course progress for students.

• Cross-Platform Player: Optimized video player (Video.js) that saves playback state and adapts to network conditions.

💳 Multi-Gateway Payment Infrastructure

• Stripe: Seamless credit/debit card processing and subscription management.

• Apple In-App Purchases: Server-side receipt validation for iOS subscription handling.

• Cryptocurrency Integration: Support for Bitcoin and Ethereum payments via CoinPayment with automated invoice generation.

• Automated Invoicing: Generation of PDF receipts and payment verification workflows.

👥 Role-Based User Ecosystem

• Student Dashboard: Access to purchased courses, progress stats, and community features.

• Admin/Super Admin Portal:

• Content Management: Upload/edit videos, manage course hierarchy.

• User Management: Monitor students, handle bans, and review verification requests.

• Financial Analytics: Real-time overview of revenue and subscription status.

🔔 Real-Time Community & Communication

• Live Community Feed: A social-media-style feed for students to discuss trading strategies, built with Socket.io.

• Push Notifications: Integrated via Firebase Cloud Messaging (FCM) for instant alerts on mobile and web.

• Newsletter System: Automated email marketing and bulk sending capabilities using SendGrid and Brevo.

• Instant Updates: Real-time notifications for payment success, new content, and community interactions.

🛠 Technical Architecture

The project follows a modern, scalable architecture prioritizing security and performance.

Frontend (The Client)

• Core: Built with Next.js 15 (App Router) and React 18 for server-side rendering and SEO optimization.

• Type Safety: Fully typed with TypeScript 5.0.

• State Management: Redux Toolkit & RTK Query for efficient data fetching and global state caching.

• UI/UX: Styled with Tailwind CSS and Radix UI (shadcn/ui), ensuring accessibility and a premium dark-mode aesthetic.

• Forms: React Hook Form combined with Zod schema validation.

Backend (The Core)

• API Runtime: Node.js with Express.js, structured for scalability.

• Database: MongoDB coupled with Prisma ORM for type-safe database queries and schema management.

• Caching & Queues: Redis for caching frequent API responses and BullMQ for handling background jobs (e.g., video processing, email sending).

• Storage: AWS S3 for secure, scalable storage of video assets and user uploads.

DevOps & Security

• Authentication: Secure JWT (JSON Web Tokens) with refresh token rotation + OTP (One-Time Password) verification.

• Video Security: Dynamic token generation for video segments to prevent hotlinking.

• Containerization: Docker-ready for consistent deployment environments.
