    Ruby on Rails Developer

    Jamaica - Last active: 6 days 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.

Sorry! :)
