Project Overview

The RoyalZSoftware Course Marketplace is a modern e-learning platform where users can securely buy, browse, and watch courses. It is built with a scalable architecture, smooth video streaming, and a user-friendly design to deliver a complete learning experience.

Technology Stack

• Next.js + TypeScript: Frontend framework for fast, SEO-friendly pages with strong typing.
• Tailwind CSS: Utility-first styling for responsive, modern UI design.
• Node.js + PostgreSQL: Backend and database powering course data, users, and transactions.
• Stripe: Secure and reliable payment processing for course purchases.
• Mux: High-quality video streaming for smooth course playback.
• Docker: Containerized services for easy deployment and scalability.
• ESLint & Prettier: Enforced clean, consistent, high-quality code.

Development Highlights

• Designed a course marketplace flow from browsing to checkout and playback.
• Integrated Stripe Checkout for one-time payments.
• Implemented Mux video hosting & streaming for high-performance video delivery.
• Applied clean architecture principles with modular components and reusable hooks.
• Used Dockerized setup for consistent local and production environments.

In this project, I built a course marketplace with payments and video streaming. The hard part was setting up Mux for video, connecting it with Next.js and the database, and running everything with Docker. I solved this by careful integration of Mux, PostgreSQL, and containerized services.
