PROFILE
Laura Ovalle Benítez
Laura Ovalle developed core backend features for the Dataflux-U-nidos/Backend repository, focusing on secure user management, scalable data models, and analytics endpoints. She implemented role-based authentication using JWT and Authorization headers, refactored domain entities and DTOs for new user types, and established robust access control for multi-tenant workflows. Her work included cascading deletes for user data integrity, campaign and education data retrieval, and dashboard APIs with mock data for analytics. Using TypeScript, Node.js, and Mongoose, Laura emphasized maintainable code through repository patterns and SOLID principles, delivering a backend foundation that supports secure operations and extensible business logic.

May 1, 2025May 2025 focused on strengthening data integrity, security, and analytics capabilities in Dataflux-U-nidos/Backend. Delivered authenticated user deletion with cascading deletes and a role-validated delete route; added total investment analytics with RBAC-protected endpoints; improved comments data model with majorId/userId linkage and DTO-consistent responses; enabled platform-wide statistics and satisfaction surveys with DTOs and end-to-end flow; launched foundational dashboard endpoints backed by mock data. These workstreams collectively enhance data governance, reporting precision, and the foundation for business insights.

Apr 1, 2025April 2025 — Dataflux-U-nidos/Backend: Delivered three core backend enhancements to strengthen security, enable scalable role-based access, and empower education data workflows. The work focused on new user roles, a refactored authentication/authorization flow, and campaign/education data retrieval capabilities. Key features delivered: - User Roles and Management System: Introduced new roles (TUTOR, UNIVERSITY, INFOMANAGER) and relationships (students↔tutors; infomanagers/viewers↔universities). Refactored domain models and updated DTOs/entities for the new roles. Commit: b7ab159c0727df77d3944e8506c9f911545bc709 (Add support for TUTOR user type) [#77]. - Authentication and Authorization Refactor: Migrated token management to Authorization header, updated DTOs/services to carry userId in JWT, and adjusted controllers to read tokens from the header for improved security. Commit: f2aa47baaf8ce0608c9af88eb25d411f44e8ab64 (Replacing cookies with authorization header) [#80]. - Campaign Management and Education Data Retrieval: Added campaigns use cases, DTOs, repositories, models, controllers, routes; refactored major entities to integrate user retrieval for creation; introduced GetMajorsByInstitution use case, controller method, and router endpoint. Commit: 0109e637ddadc6d6e99528506190aa3b716433a0 (Adds campaign use cases and controller; refactor major entity; Add GetMajorsByInstitution) [#87]. Major bugs fixed: - Security risk mitigations by removing cookie-based auth in favor of header-based JWT tokens; token handling now centralized in Authorization header, reducing CSRF risks and session leakage. - DTO/entity consistency improvements and refactoring to align with new roles, reducing data mismatches in user creation and association flows. Overall impact and accomplishments: - Strengthened security posture with token-based authentication and role-aware access, enabling safer multi-tenant usage. - Enhanced data modeling and relationships for tutors, universities, and infomangers, enabling precise access controls and streamlined onboarding of new roles. - Expanded education data workflows with campaigns and major retrieval by institution, enabling targeted program communications and analytics. - Improved maintainability and scalability through use-case driven design, controller-route clarity, and consistent DTOs/entities. Technologies/skills demonstrated: - JWT-based authentication and Authorization header usage; header-scoped token processing - Role-based access control modeling and refactoring of domain entities/DTOs - REST controllers, use cases, repositories, and router endpoints - Data-driven campaign workflows and institution-level major retrieval integration
