Facebook Messenger Engineering with Mohsen Agsen
Facebook Messenger is a chat application that millions of people use every day to talk to each other. Over time, Messenger has grown to include group chats, video chats, animations, facial filters, stories, and many more features. Messenger is a tool for utility as well as for entertainment.
Messenger is used both on mobile and on desktop, but the size of the mobile application is particularly important on mobile. There are many users who are on devices that do not have much storage space.
As Messenger has accumulated features, the iOS code base has grown larger and larger. Several generations of Facebook engineers have rotated through the company with the responsibility of working on Facebook Messenger, which has led to different ways of managing information within the same codebase. The iOS codebase had room for improvement.
Project Lightspeed was a project within Facebook that had the goal of making Messenger on iOS much smaller. Mohsen Agsen is an engineer with Facebook, and he joins the show to talk about the process of rewriting the Messenger app.

It’s hard to get engineering resources to build back-office apps, and even harder to get engineers excited about maintaining them. The idea is that all internal tools kinda look the same – they’re made of tables, dropdowns, buttons, text inputs, etc. Retool gives you a drag and drop interface so engineers can build these internal UIs in hours, not days, and spend more time building features customers will see. Visit retool.com/sedaily to learn more.
