Mobile Developer & Backend Developer CPC Notify (Colegio De la Purisima Concepcion)
Built and shipped CPC Notify, a full-stack school notification system adopted by more than 2,500 students and staff. Delivered a stable real-time client-server connection to support reliable message delivery.
Developed secure and scalable RESTful backend APIs using Spring Boot and Java. Implemented JWT and Basic Auth authentication, role-based authorization, and MongoDB data storage for user and notification records.
Created the cross-platform mobile application using React Native and TypeScript, integrating REST APIs for real-time data updates. Applied user-centered design principles to make the interface approachable for a largely non-technical school audience.
