I'm a NodeJS programmer since v0.4, and I've contributed to a large number of open-source JS projects. I'm especially skilled with Backbone (ask me about routing), SASS, tooling using Grunt/Gulp, and Browserify. My latest interest is a full server-rendering stack using Browserify and Facebook's React.
I have 5+ years of JS experience and can answer any JS questions. Additionally, if you want to get weird, I can answer questions about ExtJS / Sencha Touch and JSF/Seam (Java).
