How to program a single application that includes dozens of services without affecting performance speed

Micro-frontend architecture: Programmatically deconstructing interfaces
At Grand, we treat the Super App like a browser, and the services within it like websites. Instead of writing one massive piece of code (a monolithic app) that is difficult to maintain and slows down the device, we rely on dividing the application into completely independent software modules. Each service (such as a financial wallet or a shopping store) has its own development team and code, and it is injected into the main application as needed. This ensures that any error in a particular service does not affect the rest of the application, and it keeps the initial application size small because we only load the "core structure," and the remaining services are released when the customer requests them.

Dynamic Module Loading and Space Saving
The biggest challenge in comprehensive applications is the "app size" on the app store. The software solution for 2026 is on-demand delivery technology. We program the application to be very small in size, and as soon as a customer decides to use, for example, the "flight booking service," the application loads its module in the background at lightning speed. This saves mobile storage space and reduces data consumption. Most importantly, it allows the application to open in no time because the processor doesn't have to load thousands of lines of code for services the customer hasn't even touched yet.

Shared Resource Management and Process Sandboxing:
To ensure that dozens of services don't cause crashes, we program a strict resource management system within the application. Each service runs in an isolated environment (sandbox) and occupies a specific share of RAM and CPU. We use advanced dependency injection techniques to ensure that services share essential resources (like internet connectivity or security) without any conflicts. This technical control makes switching between services within the application seamless and without any lag, as if you were navigating through the pages of a fast website.

Unified Design System and Faster Rendering
Although the services are software-independent, they must appear as a single entity to the client. At Grand, we build a Shared UI Library, a unified interface library used by all modules. This not only unifies the look but also speeds up the rendering process because the mobile device doesn't need to load new design definitions for each service. Using modern interface technologies like Declarative UI allows for screen building with the least possible code, maintaining the app's lightweight nature regardless of its size or development time, and making it the preferred choice for users who want all their needs in a single interface.
