Mercado Libre: 18k engineers, 30k deploys a day, & their own fleet of planes | Sebastian Barrios

Sebastian Barrios, SVP of engineering at Roblox and longtime head of product and engineering at Mercado Libre, discusses how the company blends product and engineering into one role, runs on freedom and responsibility instead of OKRs, and tolerates failure while punishing poor quality. He also covers scaling to thousands of engineers and tens of thousands of daily deployments, using AI agents to build features from existing microservices, and personal stories including Steve Jobs calling him as a teenager over an app.
