Debugging an 8-Year-Old Payment System Was a Mistake...

What happens when an 8-year-old payment system silently fails for years? In this video, I and my guest Yevgeniy (Senior Software Engineer) break down a real-world production incident involving US physical check processing, a hidden SQL trigger, and a "can of worms" that led to over a million unprocessed records. We’ll dive deep into why the Outbox Pattern failed, how we traced "money leakage" through legacy code, and the hard lessons learned about QA environments and system ownership. If you’ve ever had to debug a system you didn’t build, this one is for you.
