Web Developer

I built my first website in 1996 and started working as web developer in 1997. I love building websites and helping other do the same as much now as I did then. My primary focus is Front-end Web Development (HTML5, CSS3, Sass, JavaScript, JavaScript Testing, Polymer & Web Components) and Web Performance.

Open Source projects I've authored

Web Designer

I've loved art & computers my entire life, so web design is the perfect career for me. I earned a BFA in Graphic Design, and although most of my recent work is focused on web development, I'm always collaborating with UI designers.

How can I help you?

The best ways to get in touch with me are to either email me at john [at] johnriviello [dot] com, send me a tweet @JohnRiv on Twitter, or introduce yourself to me at a meetup or conference.

Note to recruiters: I'm happily employed as an Engineering Fellow at Comcast. I was the first front-end web developer to reach that level in a technology company of over 150,000 employees. I love my job because I get to work with amazing people on technologies I love while solving big problems to improve the web experiences for millions of users. My family I love living outside of Philadelphia, not only for the family & friends we have nearby, but also for the close proximity to the ocean (and therefore, surfing). If you consider those factors, and have an opportunity that you feel is large enough to excite me, I'll certainly respect your effort to research me and reply to your request.
