Solution
I built a secure cross-platform system with role-based access, typed mobile service layers, REST APIs, authenticated messaging, and geospatial discovery so volunteers can find relevant opportunities nearby.
Features
JWT authentication and role-based access control with Keycloak
Real-time messaging using authenticated WebSockets and STOMP
Geospatial event discovery with PostGIS radius queries
Automated backend tests with JUnit and Mockito

Lessons learned
I strengthened my understanding of secure service boundaries, mobile-to-backend contracts, and how real-time features change API and authentication design.
