LASULEARN – Virtual Learning Platform

LASULEARN is a scalable, production-ready virtual learning platform designed for universities to improve course delivery, student engagement, and attendance accountability. Unlike traditional learning management systems that rely on login-based or manual attendance, LASULEARN introduces playback-based attendance monitoring, ensuring that attendance reflects actual student participation.

This project was developed as a project-based software engineering solution and validated through real user testing, system analytics, and performance evaluation.
