Message

At Mercado Libre, I develop and maintain critical backend systems for insurance, including notifications, financial activity records, policy renewals, and claims payments. I work on event-driven microservices, cloud deployments on AWS and GCP, and end-to-end observability to help prevent production incidents.

Earlier at Mercado Libre, I implemented large-scale payment processing flows in Golang for mass disbursements. I also developed Java and Spring Boot microservices at GlobalLogic and Python updates for the NSIT land registry system at Quinto Impacto.
