Uber redesigned its mobile analytics architecture to standardize event instrumentation across iOS and Android. The platform-led approach moved analytics responsibilities from feature-level code to shared infrastructure, defining standardized event types (taps, impressions, scrolls) that are code-generated from schemas and instrumented at the UI component level. Analytics builders manage event lifecycle and metadata attachment, eliminating the need for custom instrumentation. The migration reduced over 40% of ad-hoc events, improved cross-platform parity, ensured consistent metadata and semantics, and simplified querying. Automated scripts handle legacy event migration while linters prevent new non-standard implementations.
