ODesk / Elance preferred No 1 English Coldfusion Developer... Are you looking for value and quality? Then I'm your guy. I am a Senior Coldfusion Developer with 13 years experience and am also the creator of Fusemox (http://fusemox.com) - a lite Coldfusion framework that helps small-medium businesses and developers set up a well structured website quickly and with ease. I have been developing web applications primarily in Coldfusion for more than 13 years. I have a strong technical background as well as a keen eye for design which is unusual for a software engineer. My strongest skills are Coldfusion and Railo, Fusebox, MySql, XHTML and JQuery. I also have a good background in ASP.NET (C#) and SQL Server.I am self sufficient and a focused and efficient worker. I also have excellent communication skills. My strong front-end and back-end experience should make me a great addition to any web development team. I have spent the last 10 years as a full time employee, with the last 6 as the development lead and architect at a development house that did work for a government agency as well as other big corporates. I have since decided to get out of the rat race and work on a freelance basis which allows me more freedom and also allows me to gain more experience and a broader range of skills.
