During February 2026, Gabriel Reis refactored the object model definitions in the NIAEFEUP/uni repository to improve code readability and consistency, focusing on backend and mobile development using Dart and Flutter. He enhanced the serialization process by introducing robust handling of nullable parameters, which increased data compatibility and reliability across the application. Gabriel tracked and documented these changes through a targeted commit, ensuring clear traceability and maintainability. Although the work was limited to a single feature within a one-month period, the depth of the refactor addressed core data handling concerns, laying a stronger foundation for future development and reducing potential integration issues.
