reduced their code for UI components by as much as 60% using Jetpack Compose
summary
Lyft replaces its legacy UI framework with Jetpack Compose, reimplementing components to cut boilerplate and speed delivery. A button component drops from 800 lines and 17 XML files to a single Kotlin file with 300 lines, removing XML and yielding a 60% reduction in code; teams build multi‑screen flows in days that used to take much longer. Compose supports Material and custom design systems, enables server‑driven UI experiments, and now accounts for over 90% of new feature code.
