About this workshop

Speed matters. As web developers, we are charged with building sites that load lightning-fast, respond to user input quickly, and render smoothly. In this in-depth workshop, performance engineer Noah Collins will guide you through the principles and tools needed to optimize your web applications, using an example project to demonstrate each step in the process.

The workshop will start with an overview of the browser rendering lifecycle, followed by a quick introduction to analysis and measurement techniques. We'll learn how to isolate, profile, and resolve a set of progressively more complex performance challenges using an example project. Then we'll dive into applying the same practices on mobile devices. The day will culminate with a discussion of the finer points of performance: knowing when to invest in optimization and when to take a step back to re-think architecture.

Sign up today if you're ready to measure, profile, and automate your way to faster website experiences.
