    Philippines - Last active: 5 months ago - Tests: 11

    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.
