As you might know, ClassDojo offers a paid subscription for parents, to give them extra tools for interacting with both their teachers and their kids. For several years, we built and supported a system for managing those subscriptions. That’s non-trival work: it involves integrations with several app stores and payment providers and wrangling different data models for each.
In the last year, we’ve switched to a third-party solution: RevenueCat. It’s not easy switching payment systems when you’ve got several years of data in the old system, and need to keep it running until the new integration is ready to go.
I recently sat down with Urjit and Sarah, two of the engineers who led this project, and asked them about the challenges they faced and the lessons they learned as they replaced the wheels of our bus without making a pit stop. You can listen to the conversation below:
