Carlos Mendoza

Carlos Mendoza leads platform engineering at one of Brazil's largest online marketplaces, overseeing the reliability, scalability, and developer experience of a backend infrastructure that processes hundreds of millions of transactions annually. With 16 years in software engineering and a specialization in distributed systems, Carlos has become one of the most sought-after technical voices in Latin America's booming tech ecosystem. His most notable achievement came during a national retail mega-event, when he orchestrated a live platform migration while simultaneously absorbing a 40x spike in traffic — going from 1 million to 40 million daily transactions without a single minute of downtime. This feat was accomplished through a combination of database sharding strategies, circuit breaker patterns, and a custom-built load shedding mechanism his team developed in Go. The architecture he designed has since been presented as a reference case study at QCon São Paulo. Carlos is a polyglot engineer who has built production systems in Go, Java, Python, and Rust. He holds a degree in Computer Engineering from the Universidade de São Paulo and has spoken at international conferences including GOTO Copenhagen and SREcon Americas. He leads an internal engineering excellence guild that runs monthly architecture reviews and publishes a widely-read internal engineering blog. He is currently building a developer platform to accelerate time-to-production for the company's 700-strong engineering organization.
