Hello there! I’m an Engineering Manager at Stripe living in Tokyo, Japan with my family. Previously, I worked at Facebook for almost ten years where I managed the JavaScript Infrastructure and React Native teams. I built Jest, Metro, Yarn and MooTools.

I write about JavaScript, Frontend, Engineering Management, User Experience, and more. Check out my pinned post or jump into the category that’s most exciting to you:

Building a JavaScript Bundler

Jest’s packages make up an entire ecosystem of packages useful for building any kind of JavaScript tooling. “The whole is greater than the sum of its parts” doesn’t apply to Jest!

In the end, you’ll have a toy bundler, and you’ll understand the fundamental concepts behind bundling JavaScript code.

This post is part of a series about JavaScript infrastructure. Here is where we are at:
