sion, and contact pages. The admin dashboard lets staff manage students, teachers, courses, notices, events, gallery images, admissions, contact messages, users, and homepage settings like hero images. It uses SQLite for the database and is suitable as a portfolio/demo school CMS project.

workflows. The application supports four distinct user roles: customer, staff, admin, and super admin, each with role-specific dashboards and access permissions enforced via middleware. A key feature of this system is booking conflict prevention using date overlap validation, ensuring that rooms cannot be double-booked. Additionally, a structured notification escalation mechanism has been implemented, where booking requests are prioritized and escalated from staff to admin to super admin, allowing efficient handling of booking confirmations. The system also enforces strict data isolation by limiting access based on assigned hotel context. The project follows a clean architecture approach using MVC combined with a service layer to maintain scalability and readability. This project demonstrates strong backend design, real-world problem solving, and secure role-based system implementation.

g, and payroll processing. The system supports four user roles: admin, HR, accountant, and employee, each with clearly defined responsibilities and access controls implemented using role-based authorization. It enables HR teams to manage employee records, track daily attendance through structured workflows, and prepare payroll batches. A key feature of the system is its staged payroll processing workflow, where payroll data is prepared, reviewed, finalized, and marked as paid by authorized roles. Employees have access to a self-service dashboard where they can view attendance history and payslips. The application is structured using a domain-based architecture, separating core business areas such as employees, attendance, payroll, and departments. Business logic is handled using action classes, reducing controller complexity and improving code maintainability. This project demonstrates strong backend architecture design, real-world business workflow modeling, and secure multi-role system implementation.
