Matthew Liste, a senior infrastructure leader at American Express, discusses the principles of building enterprise software platforms that must always be stable, secure, and scalable (the '3 Ss'). Key topics include managing resource contention as the primary cause of scaling failures, using customer journeys to measure reliability and prioritize risk, and the challenge of balancing early vs. late technology adoption. The conversation also covers how agentic AI accelerates development speed without changing fundamental engineering accountability, the threat it poses to junior developer apprenticeship, and the importance of engineering culture, Conway's Law, and internal 'Developer Zero' teams for platform feedback.
