Worked on the openMF/fineract repository to enhance code quality and maintainability within the loan and savings modules. Focused on standardizing emptiness checks by systematically replacing size()-based logic with Collection.isEmpty(), ensuring consistency and reducing the risk of errors in critical workflows. This cleanup addressed java:S1155 issues and improved code readability, particularly in LoanRepositoryWrapper, LoanProduct, LoanStatusChangeHistoryListener, and SavingsAccount-related classes. Leveraged Java and the Spring Framework to deliver these improvements, which streamline backend development practices. The work contributed to more maintainable and reliable backend systems by unifying emptiness-checking approaches across key financial modules.
