Last year we shared how we overcame challenges to enable the successful entry of node.js at Paypal. We have gone further along in our journey, transforming what we kick started, into a self sustaining stable ecosystem. It is also important to mention, how Paypal becoming a player in the Open source node.js community, has helped renovate the internal engineering culture. I will talk about the technological improvements/experiments with node.js and community building efforts happening @ Paypal.

1. Node down the road
