When Data Moves

When Data Moves is a revolutionary work that challenges the tech industry to remember that data systems serve humans, not machines. Written by Harveer Singh, a globally recognized data and AI leader with 25 years of experience transforming financial institutions, this book reveals the invisible infrastructure that powers modern life-from coffee orders to life-saving medical transactions. This is not just a technical manual. It's a wake-up call, a love letter to engineers and executives, and a roadmap to a future where technology amplifies humanity. Through personal stories from the "data trenches," Singh demonstrates how technical decisions have real-world consequences: how storing money as a VARCHAR can prevent grandmothers from buying medicine, or how milliseconds of latency determine whether small businesses survive Black Friday. Spanning 14 chapters, the book covers data pipeline engineering, AI integration, data quality as trust, privacy paradoxes, blockchain immutability, and even planetary health monitoring. From the financial heart of payment systems to quantum computing and bioelectric integration, Singh bridges technical excellence with moral responsibility. Whether you're a 3 AM engineer debugging production, a C-suite executive making architecture decisions, or simply curious about the systems that shape our world, this book will transform how you see your work. You're not a cog-you're a cardiovascular surgeon operating on the economy's heart. Welcome to the revolution disguised as a technical book.
