Speaker: Ari Grant

Mobile Engineering Manager at Facebook
Ari Grant, an iOS Engineering Manager at Facebook, will explore how Facebook’s approach to redesigning the data layer of the app was followed by a rewrite of News Feed in the iOS app using similar functional design techniques to build a reactive UI layer with immutable objects, internal view reuse, and all view-configuration performed by the strongly instrumented, private infrastructure. He will describe the view system his team built and how they managed to reduce the code behind Feed by nearly 70%. Ari will end by describing how the team rewrote all of feed one piece at a time, all while keeping the system up and running and how these efforts have led to an even larger focus on speed and performance.
