Hi — I'm Jon.

I'm a software engineer, educator, and author of two Node.js books with Manning and O'Reilly. I've spent my career building software across web, mobile, and large-scale client systems, including work at Meta and Bloomberg.

I care about making complex technical ideas easier to understand, whether that means shipping production systems, teaching developers, writing books, or helping teams turn messy product ideas into working software.

I also run Hacky Apps, where I consult on engineering, product, and custom application development.

Elsewhere — podcast (JavaScript), Twitch: Node & web apps, Twitch: APIs.
