I am a Software Engineer. I mostly works with Linux, MySQL, Hosting Servers (FTP/MAIL/APACHE/NGINX), Nagios, Shell Scripting.
Apart from above I spent my time in android, HTML/5, CSS etc. I love StackOverflow and their other networks. For all my doubts I refer their forums.
StackOverflow members helped me in most of my doubts, and now I am trying to help others here :)
