Learning Management Web App

A Learning Management System (LMS) designed to provide an interactive and efficient learning experience. This application is built using modern web technologies such as React, Next.js, Redux Toolkit, and Framer Motion for the frontend, with a robust backend powered by Node.js, Express, and PostgreSQL. It leverages AWS services like EC2, RDS, S3, and Cognito for scalability, security, and performance, along with a CDN for fast content delivery.
