Falaq Al developed and refactored the EfferentCouplingService Test Suite in the agarasia/SER516_Spring25_Teams_3_and_4_Backend repository, using Java and Mockito to validate repository processing, data computation, and persistence. By establishing structured test scaffolding and improving readability, Falaq enhanced maintainability and reduced risk in backend data processing. On the frontend, in the agarasia/SER516_Spring25_Teams_3_and_4_Frontend repository, Falaq implemented a Vue.js loading spinner component for GitHub URL validation, providing users with clear visual feedback during API calls. This work strengthened both the testing foundation and user experience, demonstrating depth in component development, UI/UX enhancement, and unit testing.
