Developed and delivered an end-to-end emergency catastrophe and help-request management system over two months, focusing on both backend and frontend workflows within the EmergencyProject repositories. The work included designing REST APIs with Spring Boot and Java, implementing secure authentication using BCrypt, and managing data flow through DTO mapping and Hibernate. Enhanced API documentation and lifecycle governance enabled faster incident response and safer data exchange, while multi-language email notifications improved communication for help requests. On the frontend, consolidated event management and role-based access control were built using Vue.js and JavaScript, resulting in a cohesive, secure platform for NGO users and administrators.
