Developed the backend core for the RDL-FULLSTACK/VMS repository, focusing on foundational vehicle and visitor management APIs. Built using JavaScript, Express.js, and Node.js, the work established backend scaffolding and implemented endpoints for listing, adding, and deleting vehicles and visitors. The approach included creating initial controllers and integrating essential modules for authentication, user management, vehicle tracking, and visitor logging, ensuring secure and extensible admin workflows. By laying this groundwork, the backend is positioned for scalable future feature development. The engineering effort emphasized modularity and security, providing a robust base for ongoing enhancements to the vehicle and visitor management system.
