**The Swiss Cheese Defense - Multi-Layer Testing in the Age of Al Agents** Agentic AI is now producing 40% of code, dramatically increasing development flow by 10-20x, which has shifted the engineer's role to guiding agents and orchestrating the process. This rapid acceleration has overwhelmed the traditional, human-paced development pipeline, leading to bottlenecks in reviews, CI/CD, testing, and QA. To overcome this, solutions focus on "Scale Safety Nets," including scaling testing through parallel execution and ephemeral environments for every change, and enhancing deployment safety using feature flags, anomaly detection, and SRE AI Agents. Presented by Luca Bonmassar, CTO at Checkr, who leads the development of software products that help millions of people find their dream jobs while supporting a fair and safe future. With over 20 years of experience, he had excelled at creating and growing software products across various industries, including Fintech, Crypto, Social Media, and AI/Machine Learning.
