My primary responsibility involved the design and implementation of the entire cloud architecture. During that period, while most companies maintained on-premise servers, our service delivery across Latin America necessitated the migration of all servers to the United States. I spearheaded the complete cloud infrastructure migration and virtualization efforts. We leveraged Linux servers with native virtualization capabilities to host both our Windows and Linux machines. Furthermore, I engineered the network using stacked Cisco switches to guarantee high availability.
