ClyCMS

ClyCMS is a powerful, WordPress-inspired content management system built from scratch using pure PHP and the MVC (Model–View–Controller) architectural pattern. The project focuses on clean architecture, extensibility, security, and performance, making it suitable both as a learning framework and as a foundation for real-world content-driven websites.

The system demonstrates deep understanding of backend architecture, CMS design principles, and scalable PHP application development.
