My Biography

John Riviello created his first hypertext document on the Internet in 1996 and has been obsessed with building for the web ever since. He spends his days as Engineering Fellow and Lead Front-end Developer at Comcast, where he works on the Xfinity customer websites and web applications, including xFi. He loves discovering and building new tools that make web development more enjoyable and sharing that knowledge with everyone around him through speaking at conferences and facilitating workshops. He is also the author of the LinkedIn Learning course "CSS to Sass: Converting an Existing Site." In his free time, he prefers surfing waves over surfing the Internet.
