Jorge Yáñez developed the foundational architecture for the Chicken Farm Simulator in the elascano/ESPE2504-OOPSW23217 repository, focusing on establishing core domain models and a scalable UI framework. He implemented object-oriented models for entities such as Chicken and ChickenCoop, and introduced an abstract data controller to standardize operations across chicken-related features. Using Java and Java Swing, Jorge delivered the main application frame and splash screen, providing a maintainable base for future development. His work emphasized clear traceability and domain-driven design, enabling rapid feature expansion while ensuring the codebase remains organized and adaptable for evolving project requirements.
