The Challenge
An EdTech startup had a basic Moodle-based LMS that was slow, not mobile-friendly, and had no live class functionality. Instructor onboarding took 3 days, student drop-off was 70%, and there was no analytics to understand where students were struggling.
Our Solution
CodTeg rebuilt the platform from scratch on Next.js with a Python microservice backend. The new platform features WebRTC live classes, AI-generated learning paths based on student performance, gamification and a comprehensive instructor studio — all accessible on mobile.
