## Description

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.
