Why We Stopped Using AI Agents in Our Payment System | Ft Mr. Samir Ranjan Parhi | SOT02

Welcome to a deep dive into the real-world architecture of hyper-scaled payment systems. While modern engineering loves the speed and agility of microservices, cascading failures can lead to catastrophic outages. In this episode, we are joined by Mr. Samir Ranjan Parhi, Director of Infra, and Security at iServeU. He reveals the hard engineering lessons learned from scaling payment systems, why iServeU transitioned from microservices to highly reusable "nano-services", and how Kubernetes and auto-healing are replacing midnight IT war rooms. We also tackle the controversial topic of AI in software development. Samir explains why he strictly forbids interns from relying on AI before mastering the fundamentals and why treating AI as a "smart car" rather than a fully autonomous driver is crucial for maintaining secure, high-stakes infrastructure. Whether you are an engineering leader, a cloud architect, or a developer navigating the hype of AI, this conversation provides grounded, battle-tested insights.
