Building Project

Originally from a seaside town in northwestern Tunisia with high potential I decided to build a building consisting of several apartments for rental. So to join the various stakeholders in the construction but also oversee the structural work I decided to settle on the spot for 7 months.

Before the migration I listed all servers and order them by applications and completed the map of each application and network infrastructure. Then the most important step was to organize the change with the different services to limit the impact of change on the end users. After the changes I documented the changes made and update the application maps. The second contract consisted in informing the IT services about the changes and to organize the changes with them to limit the impact of my project on theirs for example during the implementation of the Cisco Nexus 1000V. My other assignment was to assist the application project managers to implement new software, for example during the upgrading of CMS Publishing software by providing new servers VM and overseeing installations.
