Wheelzy Rentals: A Car Rental System

The rising demand for short-term, flexible transportation solutions has been fueled by growing traffic congestion, increasing ownership expenses, and evolving urban lifestyles. Traditional car rental services—both offline and web-based—still encounter recurring issues such as double bookings, lack of real-time vehicle status, manual and error-prone document checks, and vulnerabilities in payment security. Wheelzy is introduced as a peer-to-peer, software-as-a-service platform designed to overcome these limitations through a secure and scalable web solution built on Python Flask with HTML/CSS and SQL integration. The system accommodates three user groups—administrators, vehicle owners, and renters—each supported with dedicated functionality. Its major components include multi-factor authentication, automated identity validation, dynamic vehicle availability tracking, seamless booking workflows, integrated payment modules, and map-enabled pickup and drop-off guidance. The platform is developed using a layered architecture that clearly separates the interface, application services, and data storage layers. Security mechanisms such as RESTful APIs, credential hashing, SQL injection prevention, and encrypted transactions are embedded across all modules. Performance evaluation under simulated heavy traffic verified high booking accuracy, rapid response times, and consistent usability. By laying the groundwork for features such as AI-driven dynamic pricing, blockchain-enabled transaction transparency, and predictive vehicle maintenance, Wheelzy represents a forward-looking approach to sustainable and reliable shared mobility.
