Our architecture is a blend of 50% app and 50% game, utilizing Swift and Kotlin for Android, and C++ for the game engine.

Our goal is to offload heavy lifting into the core to facilitate cross-platform development, which we've successfully achieved.

The Swift component creates a silky smooth native feel, while the C++ component manages the game engine, avatars, and business logic, shared between iOS and Android.

To enhance user experience, we leverage the native UI capabilities of iOS and Android, ensuring a seamless interaction.

We strive to integrate the best practices from both hardware and software development, recognizing that building mobile software can be as complex as hardware due to the need for precision and quality.

To improve innovation, we moved to a microservices architecture, allowing teams to manage their own data stores and reducing reliance on centralized resources.

We maintain a dual philosophy in our product design: everything should feel integrated while also being composable, allowing users to utilize services independently.

This architecture enables us to create various games and products by swapping out elements of Highrise, like introducing a hero collector game or an adventure fishing game.

Transitioning to a service-oriented architecture involved breaking down the monolith into independent services, which took two to three years to implement due to the lack of historical precedents.
