How Nubank Keeps Its Banking Platform Running

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
