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.

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

    With years of experience in an Helpdesk environment, I was able to develop my skills when it comes to troubleshooting Computers. I have also developed my skills in Customer Service along with the area of training and business development. These past 5 years, I have managed my own Buy n' Sell business, and also worked as a freelance IT Consultant. That's the reason why after five years of being a member in odesk, I only have 1 completed job. As an IT Consultant, I have implemented and deployed 5 Asterisk Based servers, Sugar CRM software, and NMIS. In addition to project management, I have created the training course for IT personnel based on the deployed system and have created all training materials, including system documentation and network diagram. I am seeking employment from clients that I will be able to provide technical support and even training for their employees as these are the areas that my abilities excel.  less
