Vertical Slice Architecture: Micro Frontends Across Mobile, Backend & ML

Micro frontends are often discussed in the context of web applications. But what if we extend the idea beyond UI - into mobile, backend services, and machine learning? In this talk, I’ll present a vertical slice architecture where each feature team owns everything required to deliver business value: - Android UI - Kotlin Multiplatform shared domain logic - Kotlin backend service - Python-based ML model - API contracts Instead of organizing codebases by technical layers, we organize by business features. This reduces coordination overhead, increases deployment independence, and aligns teams with product outcomes.
