Abstract: In an increasingly globalized economy, real-time access to accurate currency exchange information has become essential for international trade, travel, and digital financial transactions. This research presents the design and development of a Real-Time Currency Converter capable of delivering instant and reliable exchange rate calculations using live data APIs. The system integrates automated data fetching, server-side validation, and a user-friendly interface to ensure both accuracy and convenience. Modern technologies such as RESTful APIs, cloud-based services, and mobile application frameworks are employed to enhance system performance and scalability. Experimental results show that the proposed application achieves high efficiency, low latency, and consistent accuracy under various operational conditions. This study contributes to financial technology solutions by providing a robust model for real-time currency conversion that can be expanded to include predictive analytics and AI-driven financial insights in the future.

Keywords: Real-time exchange rates, currency converter app, financial technology, API integration, mobile application, data validation, cloud computing, fintech, live currency data.
