The problem for startups has always been producing more software faster. We've gained a ton of wisdom about this problem while cranking out our largest frontend product -- Backlot. We will share much of what we've learned about building beautiful UIs and the APIs that power them at an alarming rate. Learn about things like standalone views, our take on cross-browser woes, the best of CSS3, SASS, thin client best practices, and client side unit testing. We'd love to show you a couple of fun tools we've open-sourced along the way: shoulda.js and livecss.
