Every time you fire an API query, your beautifully crafted response comes back wrapped in JSON. But how well do you actually *know* JSON? Not "I can read it," know; I am talking about "I know exactly where the spec draws the line," know.
Buckle up. We're giving a well-deserved attention to the most successful data format the web has ever seen.

Željko has spent over 15 years in IT, mostly consulting for banks and insurance companies, with a focus on modernising legacy systems. Along the way, he developed deep expertise in JVM-based technologies and has become a go-to voice on topics such as API design. When he's not untangling someone else's technical debt, he's happily creating his own through a growing collection of personal projects he enthusiastically starts and occasionally finishes. Željko is passionate about sharing knowledge in a way that actually sticks, which usually means keeping things practical, a little entertaining, and free of unnecessary jargon.
