When Amy joined the Workplace team nearly seven years ago (back then still under the name Facebook for Work), it became clear that it would require a messaging service. While there were already a few options available, none of them was designed to be plugged into a new app. That's when Amy and her team decided to take on white labeling Messenger for iOS to turn it into what would become Workplace Chat. Amy and Pascal discuss the challenges of taking a huge app that is under constant development and adding your own functionality on top. After many years on Workplace, Amy recently switched teams and now works on Lexical, "an extensible text editor library that does things differently". To find out why you should get excited about the upcoming open source release of the library, tune in! Got feedback?
