Abstract: Legacy Customer Relationship Management (CRM) systems remain critical assets for many organizations; however, their outdated user interfaces, limited scalability, and integration challenges often hinder operational efficiency and user experience. This research explores Angular-Based Modernization of Legacy CRM Systems Through RESTful Integration Architectures, focusing on the transformation of traditional CRM applications into responsive, scalable, and maintainable enterprise solutions. The proposed modernization framework leverages Angular’s component-based architecture, dynamic user interface capabilities, and single-page application features alongside RESTful APIs that enable seamless communication between modern front-end applications and existing backend systems. By decoupling presentation and business logic layers, organizations can enhance system flexibility, improve performance, and accelerate application development cycles while preserving valuable legacy business functionalities. The study examines architectural design principles, integration strategies, security mechanisms, data synchronization approaches, and deployment models that support successful CRM modernization initiatives. Additionally, it highlights the role of RESTful services in facilitating interoperability, cloud readiness, mobile accessibility, and enterprise-wide digital transformation. Key challenges including legacy system compatibility, API governance, performance optimization, and migration complexity are also discussed. The findings demonstrate that Angular-driven modernization combined with RESTful integration architectures provides a cost-effective and scalable pathway for revitalizing legacy CRM platforms, improving user engagement, enhancing operational agility, and supporting long-term enterprise innovation in rapidly evolving digital environments.
