I have been working in a 'System and Networking' group to support servers in a mixed operating system environment for more than six years. My strengths are in installation, commission, operation and maintenance of Linux based servers and system administration. I deployed wide range of Linux servers, implemented hardening features, high availability for small to medium enterprises. I want to work in those expert areas so that I may utilize my core skills with utmost sincerity and honesty. I successfully implemented a scalable multi-branch phone/online based customer support service solution using off-the-shelf hardware and ASTERISK, Linux based the most popular open source IP-PBX sever, surprisingly at a very low cost. As part of this project, I also developed a web-based customer complaint management system integrated with ASTERISK that facilitates management to make intelligent business decision. This is a ticketing system for customer support having features of call recording, call escalation and monitoring. Moreover, I have deployed several Linux based (using Asterisk, AsteriskNOW, Elastix, FreePBX, Vicidial, GoAutodial and some mid-level wed developement) mini call center and customer support solution in home and abroad. I have some experience in web development and Smart Metering (AMR, AMI) System also. I developed the customer complaint management system using CodeIgniter PHP MVC framework & MySQL and integrated with Asterisk telephony engine. I have developed some Joomla based website also.
