#125 - Two CTO Dinosaurs vs. Today's Tech Hype with Raz Shuty // CTO @ auxmoney

Two veteran CTOs tear down today's tech hype with brutal honesty and hard-won experience. Raz Schweiger-Shuty shares his controversial approach to technical leadership at auxmoney, where he stopped a microservices rewrite and focused on business outcomes over engineering trends.

From his early days as a QA engineer to running 80-person engineering organizations, Raz demonstrates why sometimes the best technical decision is the boring one that actually works. This conversation offers a masterclass in pragmatic technical leadership for an age obsessed with the latest frameworks and architectures.

Key insights for technical leaders:
• 🏗️ Domain-driven design as prerequisite for any architectural decision
• 💰 FinOps strategies that connect engineering decisions to business metrics
• 🔄 Modular monolith patterns for teams of 40+ engineers
• 📊 Why velocity metrics are vanity and DORA metrics matter
• 🚫 Avoiding Kubernetes complexity when elasticity isn't needed
• 👥 Conway's Law applied to value stream organization
• 🔧 Platform engineering pitfalls and centralization nightmares
