Twilio is offering a preview of its TwilioCon 2013 workshops to a select group of NYC developers. The workshops will cover topics from beginner to advanced levels, connecting students with Twilio experts to gain hands-on experience using the platform. One workshop per day will be available, with extremely limited seats; interested developers should sign up promptly. A second workshop, `twilio::accelerate()', is designed for more experienced developers who want to accelerate their knowledge to expert level, covering topics such as building call queues and improving app performance through analytics.
