EduCircle: A Centralized Campus Communication and Notification Management System Using Role-Based Access Control and Real-Time Web Technologies

EduCircle successfully replaces fragmented informal campus communication with a secure, centralized, role-enforced web platform. The system achieves 100% functional test pass rate, sub-500 ms notice delivery under 50-concurrent-user loads, zero security bypasses across five attack vectors, and SUS=84.2 (Excellent). Built entirely on serverless infrastructure, it is immediately deployable without dedicated server management, making it accessible to academic institutions of any scale.
