Bad advice.

Coffeescript isnt a framework, it is a language.

So for your DOM manipulation you say you understand the quirks and difference between WebKit and IE7, what about the host of over rendering engines, mobile/tablet/desktop and different OS editions. I bet there exists dozen of bugs in your implementation. But thats how startups waste money I guess. If JQuery isnt your style use another abstraction library or a lightweight version of jQuery, combined with minification, gzipping or a CDN, rolling your own (at your current level) is just STUPID, risky and a waste of money. Typical NIH.
