Abstract

This research investigates the application of event-driven architectural patterns to bridge the gap between modern front-end interfaces and legacy back-end processing systems. Through a mixed-methods approach combining case studies, experimental implementations, and performance analysis, this research demonstrate that event-driven architectures significantly reduce coupling between system components while improving scalability, maintainability, and user experience. The findings suggest that this approach offers organizations a pragmatic pathway to modernization without requiring complete system rewrites, with observed performance improvements of 35-47% in system responsiveness and 28% reduction in development cycles for new features.
