We work in cross-platform scrum teams. Our sprint lasts 2 weeks, we use TDD, we ship to the store every iteration. Our application is used by hundreds of thousands people worldwide.
We use Kotlin as our main language, and we love it. But some parts of our product are (still) in Java.
We iterate over problems, we experiment and measure how our solutions impact the end user, and we learn how to improve at every cycle.
