Cloud Service Delivery Program Manager for 7 countries where operated Telefonica Public Cloud (Open Cloud).This service was based on OpenStack and powered by Huawei technology. Recently discontinued as a Telefonica product but migrated all customers to native Huawei Cloud services.After this change, Telefonica offers a multicloud solution involving market leaders (AWS, Azure...).

At Quersystem, as a Zimbra Gold parter, our main tasks were installing, tuning and giving support for large email environments. We have deployed infrastructures up to 30 servers for allocating more than 25000 mailboxes using several backend storage technologies as well as different physical hosts for achieving a realistic grade of HA. In most cases, the server virtualization technology used by our customers has been VMWare vSphere because is the only one officially supported by Zimbra. In fact, Zimbra was a VMWare product between versions 6 and 7. The preferred Linux distributions for these servers has been CentOS and Red Hat Enterprsie Linux (5,6,7), because of that I have large experience working with this operating system. Appart from Zimbra projects and customers, Quersystem has developed several system externalization projects (IaaS and PaaS) using different technologies, like Amazon AWS or vCloud Director. Another specific service at Quersystem was VDI deployments and migrations from an agnostic point of view, so that the customer selected the technology that fitted the most his expectations from the current market options. I also created a full featured lab in a local datacenter with 4 ESXi hsots and fibre channel storage where we have deployed our demo and pre-production environments for 3 years. This lab has been fully ported to Openstack Newton recently. These are the main projects I have worked on: - Logitravel. VDI Project for 500 remote users. - Telecable Asturias. Design and integration of a full OpenXchange environment for 30000 mailboxes. - Diputación de Málaga. High available OwnCloud for +4000 users. - Gas Natural Fenosa.
