Abstract

This thesis work focused on the proposal and execution of the refactoring of the back-end of the transactional mobile application of Cooperativa de Ahorro y Crédito Calceta Ltda. The refactoring was performed with the purpose of optimizing the code, reducing duplicity, improving readability, complying with DRY and SOLID principles, and ensuring long-term maintainability. The software development methodology used allowed a systematic and efficient approach to the refactoring process. The project was divided into stages with a detailed schedule that included planning, requirements gathering, implementation, testing and technical documentation. The results of the refactoring showed a marked improvement in the efficiency and maintainability of the system. Significant reduction of spaghetti code was achieved, duplication of methods and functions was completely eliminated, and code nomenclature and readability were substantially improved. In addition, compliance with DRY and SOLID principles led to a more robust and flexible design. The implementation of SSL/TLS certificates and other security measures were maintained and improved, ensuring a secure environment for users. The refactoring was carried out without affecting the current functionality of the mobile application. This work demonstrates that refactoring is an essential practice for maintaining software quality in critical applications, such as those used in financial institutions. The conclusions highlight the key benefits of this project and its importance for Cooperativa de Ahorro y Crédito Calceta Ltda.
