Worked on the openMF/fineract repository to refactor the SavingsEnumerations class, focusing on improving code maintainability and reducing complexity in the core domain model. Leveraged Java’s switch expression to enhance readability and streamline enumeration logic, aligning with broader efforts to mitigate regression risk. Developed a dedicated unit test class to validate the correctness of the new enumeration mappings, emphasizing robust test coverage and adherence to test-driven development practices. The work centered on Java, refactoring, and unit testing, resulting in cleaner, more maintainable code and a reduced likelihood of enum-related issues within the Savings domain of the application.
