This seems like a fine time to look back on the rather decent API platform our team built at Twitter.
Is this thing still on? Come to my #GraphQLConf talk if you're going this week. I promise it's going to be a good one.
We built a new GraphQL engine and launched it with 0 spec conformance bugs. How? Fuzz testing — finding the edge cases we didn't know to look for. James Bellenger is sharing how at #GraphQLConf 2026 @GraphQL

I am going to miss this place. We built something special here, and I do not expect to see its like ever again. I have worked here at Twitter for over 11 years. Back in July, I was the 27th most tenured employee at the company. Now I'm the 15th. I am not going to click "yes"

you did not just layoff almost all of infra and then make some sassy remark about how we do batching
like did you bother to even learn how graphql works

Replying to @elonmusk
Elon, Great chat yesterday, As you heard overwhelmingly from senior advertisers on the call, the issue concerning us all is content moderation and its impact on BRAND SAFETY/SUITABILITY. You say you’re committed to moderation, but you just laid off 75% of the moderation team! – at Manhattan, NY

This dude is laying off thousands right now, has said nothing all week, can't be bothered to sign the letter, and doesn't have the decency to keep his mouth shut for like 12 hours.
Just a truly staggering lack of leadership or decency.
I’m exceptionally proud of what our team has built over the last 5 years. It is hardcore engineering at scale, solving difficult problems, built humanely.
The team that built this platform are the kindest and most talented humans that I’ve had the privilege of working with.
Thank you.
#OneTeam
