    Mohammad Forhad Iftekher Agency Contractor

    9+ Years of experience in system administrations

    Bangladesh - Tests: 23 - Portfolio: 4

    I am a former Disney Interactive employee with 9+ years of experience on System, network administration & Information technology. I am very good with many Linux distributions like Debian, Ubuntu, RedHat, Cent OS, Fedora, PfSense. I am top notch for deploying server with LAMP ( "Linux, Apache, MySQL, and PHP ) stack for Installation, configuration, management and troubleshooting as I am doing this for last 6/7 years. I am also able to handle server for Dhcp, Ftp, Samba, Nfs or Squid proxy server. Configuring a VPN server by using PPTP or OpenVPN is a piece of cake for me. I would like to offer my clients to setup Webmin so that my clients can have a look at his own server by using graphical user interface of Webmin. I suggest my clients to have Nagios or MRTG on their server so that it gets easier for my clients to monitor their own network & server data usage. Don't think that, I am Linux driven tech personnel. I can even manage your Windows 2012 Server for Domain Controller ( Active Directory ) or any other services including different policy management with Server 2012. I can configure, manage & maintain your Exchange Server 2010 and Exchange 2013 server which you can use as a mail server though you have your freedom to use Postfix or qmail as well. Over the last 2/3 years, I had work with different VPS / VPC platforms like Amazon Web Services AWS ( EC2, S3, Route53 ), Rackspace, Linode, Digital Ocean, Ramnode, Vpsdime for my clients. I had setup hundreds of VPS / VPC and still managing them for my clients. Remote Desktop Supports is also available from me for any technical issues. You will find me easy to work with because I am well - organized, time bound and finally I got exceptional communication skills. **IMPORTANT**: While working with me, please be cool and don't show hurry on me. I believe in quality not in quantity. "Good work ain't cheap, cheap work ain't good" .
