    Hello Everyone. I am a ruby on rails web developer who loves working with creative people to make their ideas become a reality. I am driven by a passion for technology and high quality expectations for my work. I stay current by continually investigating technology trends, attending conferences, and experimenting with new libraries and plugins. I believe that personal working relationships are of enormous value when making any project a success. Due to an overload of work and personal projects I am not actively submitting bids, but may have limited hours available for the right project. Thanks.
