AI Summary
5 min readAddy Osmani spent 14 years at Google, most of it on Chrome, rising from a software engineer to a director of engineering. But his career began decades earlier, as a teenager in rural Ireland with a dial-up connection, cargo pants full of floppy disks, and a homemade web browser. In this conversation, he traces that arc, explains how Chrome DevTools became a de facto IDE, and shares his thinking on the biggest challenge facing engineers today: how to keep learning when AI makes it so easy to stop thinking.
The Browser That Built a Career
Osmani’s first big project came from a personal pain point. Growing up with slow internet, he noticed that download managers could speed up file transfers by making multiple connections to a server and downloading chunks in parallel. He wondered if the same technique could work for browsing web pages. So, at 15 or 16, he decided to build his own browser from scratch.

Addy Osmani spent more than 14 years at Google, working on Chrome, DevTools, Core Web Vitals, and most recently, AI developer experience.
If you've ever opened Chrome DevTools, or optimized a page for Core Web Vitals, you’ve used software built by Addy Osmani. In this episode, I sit down with Addy and we talk about his path from building a web browser aged just 16 to becoming a director at Google. We discuss what he learned from building tools for millions of developers, Google’s engineering culture, and why he continued doing hands-on coding work as a manager. We also get into how he works with AI agents today, the risks of ‘cognitive surrender,’ his approach to ‘loop engineering,’ and why it’s good to develop skills in product management, go-to-market, and other areas.
