Today's guest is Maude Lemaire, who is a principal engineer at GitHub and author of the book, "Refactoring at Scale."With Maude, we talked about her journey in tech, from Rent the Runway to joining Slack and leading its performance engineering team to joining GitHub as a principal engineer. And then we discussed what it means to do refactoring at scale, how to do it right, how to bring people on board, and what are the biggest mistakes you should avoid.00:01:06 Introduction00:02:05 Maude's journey in tech00:08:23 Sponsor00:09:34 Rent a Runway00:12:56 Joining Slack00:15:54 Approaching GitHub00:22:04 Changing company00:26:00 Onboarding in a big tech00:33:02 From data center to cloud00:38:22 A team for a purpose00:49:07 The biggest mistakes in large scale refactoring00:54:34 One big mistake00:57:58 Testing in production01:03:16 Test production: Big tech vs startup—This episode is brought to you by Swarmia!
