Node.js for FinTech Systems: Building Secure, Scalable and Real-Time Financial Applications
By Kenneth O. Hartley
Financial technology requires more than functional software. It demands speed, precision, security, compliance, and the ability to scale without failure. Node.js for FinTech Systems is a practical, in-depth guide designed to help developers, architects, and technology leaders build resilient financial applications using Node.js.
This book focuses on the real challenges of FinTech engineering, including real-time transaction processing, high-availability infrastructure, data integrity, fraud prevention, and regulatory compliance. Rather than covering theory alone, it provides hands-on architectural patterns and production-ready strategies that can be applied to digital wallets, payment gateways, lending platforms, trading systems, and modern banking applications.
Inside this book, you will learn how to design scalable, event-driven systems, implement secure authentication and authorization, protect sensitive financial data using encryption and tokenization, and build APIs that integrate seamlessly with banking and payment providers. You will also explore microservices architecture, distributed transactions, message queues, caching strategies, and cloud-native deployment using modern DevOps practices.
Each chapter bridges the gap between development and real-world financial infrastructure, helping you understand not just how to build systems, but how to build them securely, reliably, and at scale.
Whether you are launching a FinTech startup, leading an engineering team, or modernizing enterprise financial software, this book provides the blueprint for building secure, scalable, and real-time financial applications.
