Expert System Administrator, Expert Programmer ( Java and scripting )
Over the last 5 yrs I am working in areas like J2EE, Linux and Windows system administration which includes WebServers ( Apache, IIS ), Mail Servers ( Postfix , Exchange ),LDAP, AD, DNS, MySQL, CMS ( Joomla, Drupal, WP, Magento), Asterisk, Nagios, SMS Gateway etc.
I have done virtualization using HyperV, VmWare and VirtualBox.
Also, I have also setup security for systems using vlans, IpTables, port blocking etc.
In addition to above mentioned server systems, I have done migrations of websites from Linux to Windows and vice versa,and migrations of mail servers from postfix to exchange and exchange to office365 and vice versa.
I have setup also backups ( both enterprise grade and with small scripts ).
Till now I have worked on Labtech and Nagios to monitor and also to provide proactive maintenance to systems.
I know programming as well, so I try not to do repetitive work and hence create scripts, which results in less errors and better productivity.
I have knowledge of Java, Java script, Shell Scripting, php and SQL.
