Hi — I'm Jon.

I'm a software engineer, educator, and author of two books on Node.js (Manning and O'Reilly). I've taught in-person bootcamps in Rails and Node, and I work across web, mobile, and client surfaces at scale — not only the browser.

I've worked at Meta and Bloomberg (mobile, VR, and very large user-scale systems). I run Hacky Apps for consulting and custom work.

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