During April 2025, contributed to the Proyecto-Final repository by developing two backend policy rules to enhance investment approval processes and prevent repeated guarantees. Leveraging Java, Spring Boot, and SQL, implemented a configurable gross income threshold rule that evaluates loan and rental applications, ensuring investments remain within defined income multiples while handling null and negative values robustly. Also delivered a database-backed rule to block approvals with recent guarantees, introducing mapper changes and comprehensive unit tests using JUnit and Mockito. Refactored code for maintainability and renting context support, improving policy configurability, risk controls, and data integrity in alignment with business requirements.

The work improves risk controls, policy configurability, and data integrity, aligning with business goals of compliant and efficient loan/rental decisioning.
