Lost and Found Item System: A Cloud-Based Web Platform for Institutional Item Management Using React.js and Firebase

Managing lost and found items in institutional settings such as universities presents persistent operational challenges. This paper presents the Lost and Found Item System (LFIS), a cloud-based Single Page Application (SPA) developed using React.js v19, Firebase Authentication, Cloud Firestore, and the Cloudinary CDN. The platform enables authenticated users to submit image-linked lost and found reports, execute composite multi-parameter queries, and receive real-time listing updates through Firestore’s onSnapshot listeners. An administrative dashboard provides role-based moderation for institution staff. System Usability Scale (SUS) evaluation with 30 participants yielded a combined mean score of 81.4 (Grade B). Performance benchmarking on a 200-record dataset demonstrated first contentful paint averaging 1.74 s and composite Firestore queries averaging 1.08 s. Against the manual baseline, item logging time decreased by approximately 71% and record retrieval time by approximately 90%. The serverless architecture eliminates local infrastructure maintenance and generalizes to broader institutional resource management contexts.
