    Over the past 6+ years in the field of Systems Infrastructure & Networking, I have worked in Telecom and banking industry, with qualifications of Bachelors as well as Masters of Computer Science. Following my research into your company, there appears to be considerable synergy between your requirements for success and my achievements. I have successfully migrated 130 branches of Faysal Bank to Centralized Windows Active Directory domain via Active Directory Migration Tool (ADMT) v3.1 resulting in decreased backup cost and reduction in domain administrators. I also successfully consolidate 31 high available PTCL Services from obsolete hardware to virtualized platform resulting in USD10k as CapEx, 3-1 System admin as OpEx and USD 26k as reduced Business loss due to downtime. I have a distinction of Implementing VMware Servers Virtualization solution on IBM Blade Centre HS22 in Faysal Bank Ltd which resulted in significant decrease of OpEx.  less

    I am an Redhat Certified Linux System Engineer with more than 6 years of RICH EXPERIENCE. I can pretty much do any system admin tasks as long the OS is Linux (RedHat Systems like Fedora or CentOS and Debian systems like Ubuntu). I'm particularly good with Apache, MySQL, MySQL Replication, JBoss and DNS: I can harden/prep/optimize/install various servers in your Linux machine. I can fix almost any issues with your Apache, DNS, FTP, SFTP or MySQL/PostgreSQL server. I can setup replication for your MySQL or PostgreSQL server or fix any issues you are facing with the current replication or clustering setup. I can set up a fully function LAMP server for you. I can provide your Jboss with an Apache front-end and troubleshoot any related issues. I can set up a very efficient monitoring system for your environment using Nagios or Sitescope. I can write shell scripts for you. I can help you fix things with your web control panel such cPanel, Plesk or Kloxo. Basically, I have enough experience to fix, manage or setup your production environment (As long as they are running Linux). Thank you.  less
