Scaling a system from 66 million to over 25 billion records is no easy feat—especially when it’s a core financial system where every number has to be right, and data needs to be fresh right now.

You’ll learn how to balance high data accuracy with real-time performance, optimize your app logic, and avoid the usual traps of database scaling. This isn’t about turning you into a database expert—it’s about giving you the practical, no-BS strategies you need to scale your systems without getting overwhelmed by technical headaches. Perfect for engineers and architects who want to tackle big challenges and come out on top.
