    Philippines - Last active: 5 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.
