User Define Pre-Owned Vehicle Exchange Portal

The User Friendly Pre Owned Vehicle Exchange Portal is a premium web application written in PHP 8, utilizing a handcrafted MVC architecture. This application is created from scratch to prove architectural proficiency, avoiding frameworks and opting for a custom-built router, controller, and security middleware. This application aims to resolve existing marketplace problems, such as an uncluttered user interface, verified user listings, and security risks such as SQL injection, cross-site scripting, and cross-site request forgery attacks. These security risks have been mitigated by implementing PDO Prepared Statements, Output Escaping, and IP Rate Limiting. This application has been designed with features such as an administrator verification system, which will reduce fraudulent activity, an internal messaging system, and a favorites system for buyers. This application has been technically designed with MySQL 8 for data management, Bootstrap 5.3, and Vanilla CSS 3 for the frontend. This application has been designed with a glass morphism theme, allowing for native dark and light modes through CSS variables, providing a premium, responsive, and easy-to-navigate user interface.
