    Honesty, commitment & patience have been my strong believe for career building. It has been 12 years on job and mostly I received appreciation on my services to any work. My career began in between my education where I used to be technical instructor and server administrator. Just after the under-graduation I started working for Link3 Technologies Ltd. & still serving on. I started here as helpdesk operator and soon became useful to wireless team where I worked on site survey, point and multipoint link establishment, base station maintenance & frequency allocation and planning. Soon after that I was shifted to serve corporate customers with complicated multi environment systems & appliance on behalf as an NOC member. And so on with my growing experience and idea I started working with corporate solution analysis and implementation. My current responsibility holds me to act as a corporate solution consultant, business development & research and development. I am comfortable working with Linux, FreeBSD, Slackware, Windows etc. Worked with Cisco, Checkpoint, juniper, etc. for data centre implementation. Working with HA replication unit or cluster, VOIP system & complicated solution implementation and aggregation gets me comfort zone as a technical person. My solutions and advices are based on solving problem using existing resource with phase by phase implementation.  less
