Imagine you’re building a high-speed train—one that needs to get passengers (or in this case, financial transactions) from point A to point B in record time, with absolute precision, and without a single glitch. Now, would you let that train run at full speed without rigorous safety checks? Not. The same logic applies to financial technology (FinTech) applications, where even a minor bug can result in security breaches, compliance failures, or financial losses running into millions.
