    Senior Sales Engineer

    United States - Last active: 04/18/2014 - Tests: 7

    The age old adage of you get what you pay for has always been true of many products and services but this has never been more relevant than using oDesk freelancers. I originally singed up for oDesk to hire a freelance developer to build an application. After going through 3 different freelancers and spending over $2000 on a relatively simple app I quickly realized these discount freelancers were not able to meet my expectations. That is why I created a freelancer profile and started offering my services as an American contractor. I am located in the United States and can be contacted by phone Monday thru Friday from 9am-6pm Eastern time. I can provide phone support when needed and this is a huge advantage of working with a United States based contractor. I am currently using my IT and engineering background as a senior sales engineer selling and presenting technical products to IT departments, IT directors and C level executives. I have no problem talking to clients in person, on the phone or doing product demonstrations over a webex. I enjoy selling solutions to clients problems and showing them the value in a product. I am also involved with the marketing of products to help promote and generate leads.
