• In the engineering team, I've helped in the architecture and implementation of private cloud using VMware, NetApp storages and Cisco UCS hardware. I've used services like Puppet, MongoDB, Nginx, RabbitMQ and HAProxy. Today, the environment has more than six thousand virtual machines, with support for multi-site, multi-tenancy and IPv6. • Developed a Disaster Recovery solution using VMware, NetApp and xStream API to allow operations team to switch customers between sites. • Developed… Show more • In the engineering team, I've helped in the architecture and implementation of private cloud using VMware, NetApp storages and Cisco UCS hardware.
