How Nubank Keeps Its Banking Platform Running

What this episode covers

Episode 13 of The CTO Podcast explores how Nubank, the Brazilian digital bank with over 100 million customers, maintains 99.99% uptime on its core banking platform. Lucas and Luna break down the specific architectural decisions that power Nubank's resilience: from its custom-built transaction engine to its chaos engineering culture. They discuss how the company reduced mean-time-to-recovery from hours to minutes, and why Nubank treats its database schema changes like code deploys. A rare look inside one of the most operationally rigorous fintech stacks in the world. #Nubank #Fintech #ChaosEngineering #BankingPlatform #Uptime #Microservices #DatabaseSchema #MTTR #Resilience #Brazil #EngineeringCulture #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #CTOPodcast #SystemArchitecture #TransactionEngine #IncidentResponse Keep every episode free: buymeacoffee.com/fexingo
