Load all content above the fold first

We saw a 500ms win when migrating features and content to load ATF, increasing sales by 5%.

Server side render everything

amazon.com is server side rendered and has no client side rendering framework. The potential latency hit didn't justify it.

We were stuck with jQuery 1.6.4 😬

SSR React wasn't fast enough for us. This blew my mind.

Track critical performance metrics

We tracked:

• time to load content above the fold
• time to first suggestion
• time to visual completeness
• time to load ads
• time to page layout ready
• and many more...

Tech recruiting is so broken that I had to remove my college education from LinkedIn to land my first job.

Here's why 🧵

Before I graduated college, Google, Amazon, PayPal, and many other companies were using my open source software. I'd been writing software long before I started college.

After I graduated, I knew I wouldn't feel challenged in a fresh grad role. I knew I could skip a SWE level but the FAANG recruiting machine doesn't account for edge cases.
