Quick course introduction

What You’ll Learn

In this lecture series, you'll gain a solid understanding of front-end web performance that'll enable you to deliver sites quickly and reliably.

Is This For Me?

This lecture series is adapted from an all-day workshop that I gave at conferences throughout this year. It is designed to cover performance holistically, starting with the basics and continuing to touch on points both technical and not. The course does not assume any knowledge of performance concepts, but it is aimed at Front-End Developers and UI/UX designers who are comfortable writing HTML, CSS, and have a basic knowledge of JavaScript.

If you're a designer or developer looking to gain a better understanding of how your decisions and company culture impacts your ability to deliver quickly and resiliently, this is the course for you.
