System Blueprint

Enterprise Multi-Module Banking Architecture

Decoupled Android & iOS Architecture for Banking (MBank, NIBL Thaili, ADBL Kisan)

Designed a clean separation of concerns separating feature modules, core business domains, localized crypto-storage, and platform bridges. Reduces compile time, eliminates cyclic dependencies, and isolates critical banking security logic.

Key Technical Impact

Dynamic feature delivery and reduced APK download size
Bank-grade SSL Pinning & Keystore encrypted token caching
Sub-second startup time and 60 FPS smooth transactional UI
Decoupled testability with mockable domain repository layers
