I work on products at Facebook and get a lot of questions from friends and family about how we choose what to build. After 6+ years at Facebook focusing on continuous iteration and improvement, I'd like to share my thoughts on how we think about testing and launching products. Read more...

We introduced video calling today. It's my first project since joining Facebook in the Seattle office nine months ago. It was an exciting challenge to create a way for people on Facebook to instantly call any friend or family member anywhere in the world. Read more...

Facebook Chat usage has increased steadily since its launch last year, and this week we reached 1 billion messages sent per day. As a team we've been looking forward to this milestone; we track lots of statistics in the course of maintaining and improving Chat, but this number measures Chat's progress toward its ultimate goal: increasing communication between our users. We've invested a lot in making Chat stable and scalable in the past, and we continue making improvements even now. Read more...

Almost ten months ago we launched Facebook Chat to 70 million users. We ventured into a lot of new territories with this product: not only were there tricky web design and product issues, we needed to develop and launch a trio of new backend services to support all of Chat's functionality.

The All-Night Hackathon Is Back!

Posted about 9 years ago
blog post · Culture · Web · Mobile · Hacking · Performance · User Experience · Chat

Every few months, our engineers unleash their talents in one epic, all-night coding session. These are the Facebook Hackathons. They start with takeout Chinese food around 8 p.m. and end with a dawn breakfast at any pancake house or donut shop that will have us. In between, dozens of Facebook engineers create working prototypes of projects that they always wanted to build but couldn’t ever pursue during their regular hours. Hackathon XI – also known as The Presidential Hackathon – will take place the evening of Wednesday, Nov. 5. Read more...

Facebook Chat

One of the things I like most about working at Facebook is the ability to launch products that are (almost) immediately used by millions of people. Unlike a three-guys-in-a-garage startup, we don't have the luxury of scaling out infrastructure to keep pace with user growth; when your feature's userbase will go from 0 to 70 million practically overnight, scalability has to be baked in from the start. The project I'm currently working on, Facebook Chat, offered a nice set of software engineering challenges:. Read more...
