Worked on the SQLutions-FATEC/API-3-Semestre-Backend repository to enhance data integrity and API reliability for contract management. Focused on standardizing DTO naming conventions and aligning data mapping across ContractRequestDTO, ContractResponseDTO, and ContractServiceImpl, ensuring consistent data flow and predictable API behavior. Addressed a contract lifecycle edge case by refining the inactivation logic so contracts are not erroneously active on their inactivation date. Utilized Java and Spring Boot, applying the DTO pattern and targeted refactoring to improve maintainability. The work reduced the risk of inconsistent contract states in downstream systems and strengthened the backend’s overall reliability and data consistency.
May 2025 – SQLutions-FATEC/API-3-Semestre-Backend: Delivered key data-model and API reliability improvements. Standardized ContractRequestDTO naming and aligned data mapping across ContractRequestDTO, ContractResponseDTO, and ContractServiceImpl; fixed contract inactivation end-date to prevent edge-case active contracts on inactivation date. These changes improve data integrity, API consistency, and contract lifecycle correctness.
