    Over the last 5 years I have developed Linux administration and Oracle database administration skills. I am efficient in both standalone and clustered database environments. Both environments have also allowed me to gain experience in areas that include Oracle RMAN for backup and recovery, Oracle Data Guard to deploy standby databases, Oracle Active Data Guard which allowed me to use the previously referenced databases to offload processes such as reporting and backups to free up the primary databases for application transaction processing. My main objective using oDesk is to help Mills Information Systems network and start a project portfolio in order to get their foot in the doors of the Information Systems community. We look forward for working with a wide variety of clients and their data needs.  less
