Lean async code with Kotlin´s coroutines
summary
Shows concrete Kotlin coroutine patterns used at Gett: using Retrofit for network calls, launch + Job to run two reverse-geocode calls in parallel, using async/await + select to return the first provider result (Google vs startup), wrapping jobs in a lifecycle-aware job cancellor to auto-cancel on destroy, and replacing BroadcastChannel boilerplate with a dataStore/dataStream abstraction. Demo code runs, simplifies sequencing, and improved readability and lifecycle safety.
