01 · About

A developer who likes to explain things.

Coding since 2013

— Bio

Hey there! I'm Kadi, and I've been building things on the web (and beyond) for over a decade now. These days I work at Expo, where I get to help make React Native development smoother and more enjoyable for everyone.

I'm a bit of a teaching nerd - I've created courses for Frontend Masters and Egghead, spoken at conferences all over the world, and I genuinely love breaking down complex topics into something approachable.

When I'm not knee-deep in code, you'll probably find me at a conference, recording a tutorial, or figuring out how to explain yet another routing concept.
