Hirumi Senevirathna developed JWT-based authentication for the sankadslt/Debtx-frontend-Drc repository, focusing on securing DRC Case APIs that handle mediation cases, customer contacts, and settlement details. By standardizing token handling within CaseService.js, Hirumi addressed security inconsistencies and established a foundation for scalable role-based access control. The implementation used JavaScript and emphasized API integration and authentication best practices, aligning the frontend with enterprise security standards. Although the work spanned a single feature over one month, it demonstrated depth by consolidating authentication logic and introducing user roles, setting the stage for future enhancements in access control and frontend security architecture.
