Smart roadmap that shows how OkCupid rewrote their API from REST to GraphQL.
He makes a couple of good points, including how to repick your variable names. He also discussed creating the new call as a shadow request, which I found very interesting.
Handy roadmap with some strategies any technical folks making changes to their software.
