Overview

The E-Learning Platform is a robust and scalable web-based application designed to facilitate online education for students, instructors, and administrators. The goal was to create a secure and feature-rich system that could support real-time learning, course management, and progress tracking — all built on a solid backend foundation that ensures reliability, flexibility, and scalability.

As the backend developer, I led the development of the server-side infrastructure, managing user roles, data interactions, real-time features, and seamless third-party integrations.

Key Backend Responsibilities

Role-Based Access Control

  Designed and implemented a secure user authentication and authorization system with multiple roles: admin, instructor, and student — each with distinct permissions.

Course & Content Management System

  Created APIs to allow instructors to upload video lectures, create quizzes, and structure modules, while students could enroll in and track course progress.

Progress Tracking & Reporting

  Built logic to track lesson completion, quiz scores, and course achievements, and developed APIs to generate personalized learning analytics and reports.

Real-Time Notifications

  Integrated real-time notifications using WebSockets to alert users of new assignments, live sessions, and discussion replies.

Secure Payment Integration

  Enabled monetization by integrating Stripe for course purchases, subscriptions, and instructor payouts.

Scalable Architecture

  Used containerized services and horizontal scaling techniques to prepare the backend for high user loads during peak times (e.g., live classes or assessments).

Impact

The backend system of the E-Learning Platform delivers a secure, seamless, and data-driven experience for learners and educators. It powers a growing user base with real-time capabilities, in-depth tracking, and reliable performance. This project honed my skills in building educational tools that adapt to diverse learning needs while maintaining strong architectural principles.
