Educational Learning Management System

⚠️The Problem

Educational institutions in Tunisia needed a comprehensive digital platform to manage courses, students, assessments, and communications. The platform had to support Arabic RTL, handle complex educational workflows, and work seamlessly across web and mobile devices.

✓My Solution

Built a microservices architecture with 10+ specialized services: student app, instructor portal, admin dashboard, mobile apps, messaging system, library, internship management, and more. Implemented Next.js 16 for performant web experiences and React Native for native mobile apps.
