International Convention Registration & Management System

Problem: The convention required a reliable system to handle large volumes of local and international registrations, track attendee details, manage accommodation information, and support administrators with real-time visibility and control. Manual or fragmented registration methods were inefficient, error-prone, and difficult to scale.

Solution: Designed and developed a full-stack PHP-based web system using MVC principles. The system enabled online attendee registration, secure data capture, and centralized storage in a MySQL database. Implemented admin authentication, role-based access, and CRUD functionality for managing registrants. Used Bootstrap and custom CSS for a responsive, user-friendly interface, and JavaScript to enhance interactivity and form validation.

Result: Successfully supported registration and tracking for an international convention, improving data accuracy, reducing administrative workload, and enabling organizers to manage attendees efficiently from a centralized dashboard. The system streamlined the entire registration process and proved stable under real-world usage.
