Having been in the web development game since before most colleges offered courses on the topic, John has seen it all. He started tinkering with computers from an early age and ended up sticking with it for over two decades, building web pages since the Internet’s early days. But John’s tools and attitudes are anything but outdated. He has worked on an augmented reality startup, dreams up new uses for blockchain technology, and studies how Markov chains are used by AI to generate everything from short stories to pop songs. A self-professed nerd, John has an insatiable appetite for learning and a bad habit of buying books, with thousands of them now crammed into his home. He’s hardly someone to pick on, though; when he’s tapped out from reading text on pages and screens, he makes use of his third-degree black belt to teach jiu jitsu.
