During a two-month period, Jumizusu developed core backend features for the Dataflux-U-nidos/Backend repository, focusing on both comment management and user authentication. They built a Comment Management System with robust data contracts, CRUD operations, and validation, then refactored schemas to standardize DTO usage and improve maintainability. In the following month, Jumizusu implemented a user authentication system with session management, logout, and JWT refresh token support, centralizing token handling for enhanced security and scalability. Their work leveraged TypeScript, Node.js, and Express.js, emphasizing interface-driven design, dependency injection, and repository patterns to ensure code quality, testability, and future extensibility.

In April 2025, delivered foundational authentication enhancements and key refactors for Dataflux-U-nidos/Backend, focusing on secure session management, logout, and a robust JWT lifecycle. The work strengthens security, improves maintainability, and paves the way for scalable client integrations.
