How does a large-scale app evolve its Android architecture? This workshop explores how applications transform from traditional MVVM to event-driven patterns, improving testability and significantly reducing state-related bugs.
Participants will build a feature using three architectures that power large-scale apps: MVVM (a common starting point), MVI (the current standard), and Workflow (for complex state machines). These patterns are battle-tested in high-traffic production environments
Starting with MVVM, we'll recreate common production bugs: race conditions, state inconsistencies in search results, and untestable ViewModels. Then we'll refactor using MVI, implementing a single-state approach with pure reducers that make features predictable and testable, Finally we would take a look into workflow, an architecture designed for complex user journeys for the purpose of software clarity, correctness and testability (especially at scale)
You'll gain practical insights: why certain patterns are chosen, how to migrate features without disrupting users, and common pitfalls to avoid. Most importantly, you'll take home an architecture decision framework – the systematic approach for choosing the right pattern for each feature.
Perfect for developers facing scaling challenges or teams evaluating architecture changes. Learn from real production experience borrowed from practical lessons working at getyourguide, not theoretical examples

Architecture at Scale: From MVVM to Event-Driven Patterns - A Production Journey

Kotlin Coroutines offer a powerful and efficient way to handle concurrency in Android applications. This workshop will guide developers through advanced coroutine concepts, structured concurrency, dispatchers, custom scopes, error handling, graceful cancellation, and reactive programming with Flows and Channels. Through practical examples and live demonstrations, participants will build a chat application live, gaining in-depth knowledge of coroutine usage, enabling them to build scalable, responsive, and robust Android applications.
