E-Learning Platform Migration

National Technical University of Athens (KEDIVIM)

The Challenge

The university's Center for Continuing Education (KEDIVIM) operates a learning management platform serving 37+ courses and over 3,000 users. The existing WordPress-based system, despite regular updates, presented persistent security vulnerabilities inherent to the platform. Dependency on third-party plugins created maintenance overhead, performance bottlenecks, and limited customization options. The institution needed a modern, secure, and scalable solution.

The Approach

We developed a comprehensive migration strategy focusing on security and performance:

  • Security-First Architecture: Moving from WordPress to a custom Next.js 14 application eliminates plugin vulnerabilities and reduces attack surface
  • Headless CMS: Payload CMS provides flexible content management without frontend coupling
  • Modern Stack: Next.js 14 with MongoDB offers superior performance and developer experience
  • Phased Migration: Course content and user data migration with zero downtime approach

The Solution

A custom-built learning platform designed specifically for KEDIVIM's needs. The architecture eliminates dependency on third-party plugins, provides granular access control, and enables rapid feature development. The platform supports course management, user enrollment, progress tracking, and certificate generation.
