Katie and Shelby are both passionate about functional programming and Kotlin! Both recently made the move cross country from the west coast to the east coast to start their new roles. Shelby is starting a new job as a software engineer at Twitter. She will be working on the search infrastructure team focusing on backend development. Previously, she worked at Intuit. Katie is a software engineer working on a backend service providing fit recommendations for Amazon Fashion. Katie also previously worked at Intuit on TurboTax Online. In this episode we discussed with Shelby and Katie how best to effect change across an organization, especially when the goal is to introduce functional programming. We had a chance to learn from Shelby and Katie how they brought functional Kotlin to Intuit, and effective methods to level up on FP principles. We also had an interesting discussion around whiteboards and the interview process, and had the chance to hear their thoughts on microservices.
