Take back-ups of Oracle and SQL Databases, File Server and Windows Server OS state. Key Accomplishments Upgraded all Window Server Operating Systems from Windows NT and 2000 to Windows 2008 Enterprise that helped in centralizing network resources, provided single username database and ensured improved security and performance. Initiated the plan for consolidating servers in a datacenter for improved safety, security and ease of management and troubleshooting. Reengineered the network topology of the hospital by segmenting it into Virtual LAN (VLANs) that resulted in reduced administration costs associated with moves, adds, and changes, controlled broadcast activity, improved network security, leveraged existing investments and provided scalability. Instrumental in eliminating 95% of computer and data/voice communication downtime by introducing and installing interruptible power supply and configuring redundancy strategy. Implemented best practices in Cisco Networking Technologies such as VLAN, Layered Network Topology for scalability and consolidating network devices, redundancy strategy and VTP for centralizing and automating network devices administration, modification and troubleshooting. Introduced and implemented secure VPN connection for vendors and application support. Recommended and implemented the use of wireless bride point-to-point connectivity to online remote clinics in accessing hospital and patient information as well as registration. Implemented and configured external and internal messaging system by using Microsoft Exchange 2007 Server. This expedited collaboration, saved courier manpower and reduced paper usage by 80%. Successfully implemented Squid Linux based Secured Internet Proxy Server by sharing one internet connection to more than 600 computers.
