Key Technical Decisions
Why Java?
"Chose Java to design a strongly structured backend with clear service layers and scalable architecture suitable for enterprise LMS systems."
Why PostgreSQL?
"Relational structure fits course, exam, and reporting data while supporting complex queries for analytics and performance tracking."
Modular Service Design
"Separated courses, exams, reports, and AI assistant into modules for maintainability and future scalability."
Legacy Bottleneck
Many LMS platforms focus on UI but lack structured backend workflows for exams, reporting, and content management. I built this project to design a production-style LMS backend with scalable architecture and clear module separation.
Proprietary Solution
Developed a modular Java backend with PostgreSQL supporting course creation, quizzes, exams, enrollment, reporting, blogs, and an AI assistant. The system is structured to simulate real-world LMS workflows with admin and student roles.
The project demonstrates a production-style LMS backend with structured workflows for courses, exams, and reporting, showcasing backend architecture and system design skills.
