Diogo Guerra (SVP Engineering Feedzai)

We talk with Diogo Guerra about building fraud and risk platforms at global scale while keeping engineering speed high and security standards uncompromising. We dig into why security leadership sits close to engineering at Feedzai, how they operationalize threat modeling, and where AI helps or hurts productivity. • Diogo’s scope across engineering, security, IT, and cloud operations for a 190-person organization • Feedzai’s focus on transactional fraud, anti-money laundering, and identity intelligence using behavioral and device analytics • Why SaaS responsibility and tier-one bank expectations raise the security bar • Balancing developer velocity with open source risk using context-driven vulnerability management • Rapid mitigation playbooks across thousands of servers without stopping delivery • Nonnegotiable security gates including threat modeling before major production changes • Bringing AI into the full development lifecycle with shared context and curated skills • A small architecture group distributing AI setups and productivity patterns across teams • Managing token cost, model choice, and avoiding lock-in as AI usage scales • How Gen AI amplifies social engineering scams and why identity signals matter • What agentic commerce could mean for fraud detection and cyber-fraud convergence
