How Learmy (learmyeducoach.com) scaled video streaming, live quiz evaluation, and multi-trainer scheduling to support 10,000+ active learners across India.
Building a modern Learning Management System (LMS) requires balancing rapid feature deployment with bulletproof scalability. When thousands of students log in concurrently to attempt live mock exams or stream HD lectures, database latency can kill user experience. Here is how we engineered Learmy LMS.
Rather than jumping straight to complex microservices, Learmy is built on a modular Laravel Domain-Driven Design (DDD) architecture. Core modules (WhatsApp, AI Planner, Live Classes, Quizzes, Billing) operate in strict boundary contexts with clean internal DTO interfaces.
Course content protection is critical for course creators. Learmy encodes uploaded video files into HTTP Live Streaming (HLS) chunks with AES-128 encryption and dynamic student watermark overlays, preventing screen-recording and direct download piracy.
During competitive exam prep sessions, 5,000+ students submit quiz responses within seconds of the timer expiring. Learmy offloads score calculation and rank generation to background Redis job workers, maintaining sub-50ms HTTP response times for quiz submit actions.
A well-structured modular monolith combined with async Redis queues provides 99.99% reliability without the overhead of microservices orchestration.
