Hi, I'm Rui and welcome to the App Performance Cafe, a podcast focused on mobile app performance. This week we had the pleasure to have as a guest Thomas Harman, Engineering Manager at Pinterest. Tom is responsible for ensuring that Pinterest performs always at the top of the industry. Tom shares with us why and how one must ensure that everyone in the company is on the same page regarding performance. Tom also shares advice on how can we detect changes in performance, in particular, what can be detected pre-release, and, more challenging, what cannot. This also correlates a lot with how should we measure and analyze performance. A long one, we know, but we hope you do enjoy the episode.
