    Jamaica - Last active: 1 day ago - Tests: 5 - Portfolio: 8

    Ranked among the top oDesk contractors from Jamaica for Q1 2012 and represented oDesk at a local job fair. oDesk - "We commend him on his success and thank him for sharing his experiences here" [See Digital Jam 2.0 in Portfolio for my guest blog post plus links to my presentation] I started programming back in 1998 in high school and I was hooked. My search for the best development framework ended when I started Ruby/Rails in 2006. Finally a framework that is designed out of the box to work they way I program (DRY). I'm looking for interesting/challenging TDD Ruby on Rails projects. Being good at unix gives me the advantage of being well able to do deployments, from as easy as Heroku to Capistrano style deployments.
