How One Startup Uses Dependency Graphs to Prevent Outages

Episode 50 of The Technical Co-Founder Podcast. Lucas and Luna explore how a growing fintech startup reduced production incidents by 40 percent by modeling their entire microservice architecture as a dependency graph. They walk through the specific tooling — an open-source graph database called DGraph — and the cultural shift of making every team own their upstream and downstream services. They discuss how the graph caught a critical cascade failure during a routine database migration, how the company visualizes blast radius before every deploy, and why the CTO compares it to a city's subway map. If you're an engineering leader wrestling with microservice complexity, this episode gives you one concrete pattern to try next week. #DependencyGraph #Microservices #OutagePrevention #GraphDatabase #DGraph #BlastRadius #SiteReliability #EngineeringCulture #TechDebt #IncidentResponse #SoftwareArchitecture #CTO #Fintech #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #TechnicalCoFounder #EngineeringLeadership Keep every episode free: buymeacoffee.com/fexingo
