    Ruby on Rails Developer

    Jamaica - Last active: 5 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.

    Flash/Actionscript, HTML5

    United Kingdom - Last active: 20 hours ago - Tests: 9 - Portfolio: 1

    I first started programming with HTML, CSS, Javascript, MySQL and PHP in a Linux environment, and I now use these skills for HTML5 programming. I have also worked on a wide range of Flash/Actionscript projects and I find Adobe Flash Professional is particularly advantageous for high-specification multimedia programs - both for online and desktop applications. I have experience of game design, and I am confident that I can contribute to the creative design process. I have also worked on a series of multi-player games for a client using the XIFF/Jabber chat server. I have teaching experience and I would welcome the opportunity to get involved in online/virtual teaching in addition to software development opportunities.

    Ruby / iOS Developer

    Philippines - Last active: 4 days ago - Tests: 12 - Portfolio: 2

    Plain and simple, to get the job done! Fancy words and jargons may sound good but I prefer letting my skills do the telling, more so the talking. As an undergrad, I spent my years doing personal projects which most of the time are irrelevant to our curricula. But since I firmly believe experience is the best teacher, I 'do' rather than just think about it. Long story short, I dropped out of college to get things done. I primarily focus on Ruby(Rails) development but I also have experience with node.js. Technologies that I've used include Coffeescript, SASS/LESS, socket.io, express, and rails gems e.g. Devise, CanCan, Paperclip, etc.. As a freelancer, I had worked with various clients where I have showcased the skills that I have in every applicable way. For instances where I'm new to a task I'm assigned to do, I went out of my way to make sure I have sufficient knowledge before starting with the job. Previous experiences include SEO, Virtual Assistance, various Research, Wordpress Installation, Content Moderation, and Landing Page design.
