The Challenge
Building a comprehensive LMS from the ground up that handles student lifecycle management, real-time attendance tracking, course content delivery, and performance analytics — all while maintaining a clean, intuitive interface for both administrators and students.
Architectural Decisions
◆Role-Based Access Control
Implemented granular RBAC with admin, instructor, and student roles — each with scoped permissions across the entire platform.
◆Real-Time Dashboards
Server-side rendered dashboards with incremental data fetching for instant insights on student performance and attendance trends.
◆Modular Course Engine
Designed a flexible course creation system supporting multiple content types, scheduling, and progress tracking per student.
◆Scalable Data Layer
MongoDB with indexed queries and aggregation pipelines for fast analytics across thousands of student records.
