I have develop web since 2009 and full time remote freelancer since 2011. Beside RESTful app (single page or responsive web app), data visualisation are also my favourite field to develop, I always enthusiast when I must work with both of them. My common toolbox are including (but not limited to) Ruby on Rails, Backbone.js, Marionette.js, Angular.js, Ember.js, Highcharts, D3.js, MEAN.JS, Express.js, Mongoose, Socket.io, Jade, Handlebars, Grunt, Gulp, npm, bower, etc. I also have good understanding on algorithm, data structures, design pattern, basic math and physics (useful for game development). And those fundamental knowledge very helping me in deliver high quality app with efficient code. I'm able to be working on *nix (Mac OS) & Windows environment. Please check my GitHub account to see my open source works and contributions. I also use GitHub to watch several popular open source libraries. Now I'm full time freelancer, so I prefer long term and/or full time telecommuting job. I'm a LOYAL freelancer, so if you have full time workload, I can stick with you for a long time without applying a new job. Thanks,
