Marcos Ayelen developed foundational parcel management and security features for the buzon-inteligente-BE repository, focusing on scalable locker-to-parcel workflows and secure access code operations. He introduced a Parcel entity and extended the Locker model to support time-based delivery constraints, establishing robust data relationships for future enhancements. Marcos also built an Access Code Management API with dedicated controllers and DTOs, enabling automated access control. Addressing authentication reliability, he resolved Base64 decoding issues and refined security configurations to ensure proper endpoint access. His work demonstrated strong backend development skills in Java, Spring Boot, and Hibernate, delivering maintainable, audit-friendly code with clear commit history.

April 2025 (Eureka-projectFactoriaF5/buzon-inteligente-BE) - Delivered foundational parcel management and security enhancements to enable scalable locker-to-parcel workflows and secure access code operations. Key features delivered include the Parcel and Locker Management System (Parcel entity; Locker extensions for parcel deliveries with time-based constraints and data model relationships) and the Access Code Management API (new controller, DTOs, POST endpoint, and entity-to-response mapping). Major bug fixes address authentication flow reliability (updateProfile Base64 handling) and security configuration to ensure correct endpoint access. Impact: accelerated delivery operations, improved data integrity, new automation-friendly access controls, and a more robust security posture. Technologies demonstrated: Spring Boot REST APIs, Entities/DTOs/Controllers, data modeling of Parcel-Locker relations, time-based constraint logic, and authentication security hardening.
