Marcel M. Agency Contractor

Ruby on Rails Developer

Jamaica - 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.

Kevin C.

Kevin C. Agency Contractor

Ruby / iOS Developer

Philippines - 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,, 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.
