In this talk, we'll dive deep into techniques for creating a truly optimized modular setup that balances independence, scalability, and build-time performance. You'll learn: - How to design module relationships to minimize dependencies and reduce build times. - Strategies for leveraging custom Gradle plugins to enforce consistency and simplify configuration. - The power of version catalogs to manage dependencies across modules effortlessly. - A cutting-edge navigation system enabling seamless transitions between modules without direct dependencies. This session combines practical coding techniques with real-world architectural insights, equipping you with actionable ideas to improve your project’s modularization. Attendees will walk away with tools, tips, and strategies they can apply to their codebase immediately. ## Speaker ### [Mohamed Gamal](https://www.wearedevelopers.com/@mohamed-gamal) Mobile Staff Engineer at SumUp ## Related talks at this congress - [Building Modular Applications with .NET and ABP Framework](https://www.wearedevelopers.com/events/world-congress-2025/sessions/473-building-modular) — Halil İbrahim Kalkan - [A Practical Guide to Reducing Bundle Size](https://www.wearedevelopers.com/events/world-congress-2025/sessions/722-a-practical-guide-to) — Stephen Cooper - [Building Better Apps with React Native](https://www.wearedevelopers.com/events/world-congress-2025/sessions/785-building-better-apps) — Marc Rousavy - [Advanced Micro Frontends: Multi-Version and Multi-Framework Scenarios](https://www.wearedevelopers.com/events/world-congress-2025/sessions/501-advanced-micro) — Manfred Steyer
