# About

I'm **Vojta Holik**, co-founder of [badass.dev](https://badass.dev/) and the design engineer behind some of the most successful developer courses on the internet.

Since 2018, I've been building custom course platforms with [Joel Hooks](https://x.com/jhooks) ([egghead.io](https://egghead.io/)) using our own CMS, Course Builder.

I've helped creators like **Kent C. Dodds** and **Matt Pocock** teach millions with fast, opinionated platforms used by teams at **Apple, EA, Netflix**, and more.
