Cloud-Native Intelligent Quality Assurance and Predictive Analytics for API-Centric Financial Systems Using Machine Learning
Main Article Content
Abstract
Financial institutions increasingly rely on Application Programming Interfaces (APIs) to facilitate secure, real-time interactions among banking applications, payment gateways, investment platforms, and third-party financial services. As API-centric architectures grow in complexity, ensuring software quality, reliability, security, and operational efficiency becomes increasingly challenging. Intelligent Quality Assurance (IQA) combined with Predictive Analytics powered by Machine Learning (ML) provides an innovative approach to addressing these challenges. This study explores the integration of machine learning techniques into quality assurance processes within API-driven financial ecosystems. Intelligent QA systems utilize automated testing, anomaly detection, defect prediction, and performance monitoring to identify potential issues before deployment. Simultaneously, predictive analytics models analyze historical transaction data, API logs, user behavior, and system performance metrics to forecast failures, security threats, and service disruptions. The research investigates the effectiveness of supervised and unsupervised learning algorithms in enhancing testing accuracy, reducing operational risks, and improving customer experience. Furthermore, the study highlights the role of real-time monitoring and predictive maintenance in ensuring regulatory compliance and system resilience. Results indicate that machine learning-driven quality assurance significantly improves defect detection rates, reduces downtime, and optimizes resource utilization. The findings demonstrate that integrating intelligent QA and predictive analytics strengthens the reliability, scalability, and security of modern financial systems operating within API-centric environments.
