Ridho Alrahmi developed the Rental Extension Management feature for the ridhofrd/monitoringTeltonika repository, focusing on seamless integration between backend and frontend systems. He designed and implemented backend API endpoints using Node.js and PostgreSQL to fetch and update rental extension data, ensuring robust data handling and clear API contracts. On the frontend, Ridho built React components and modal interfaces that allow users to view current rentals and initiate extensions, streamlining the extension workflow. Throughout the month, he prioritized code quality and integration, updating the client-facing service layer without introducing major bugs, and delivered a cohesive, end-to-end solution for rental management.
