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 ... morehave 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. less
