Architecture

The systems thinking behind every product.

This is the craft I care about most — the patterns, data flows and pipelines that make enterprise mobile fast, testable and resilient.

Clean Architecture

Domain-centric layering with strict dependency direction

Every enterprise app is built with a clear separation between domain, data and presentation. Business rules live at the center and never depend on frameworks or UI, making the system testable, portable and resilient to change.

PresentationScreens, components and MVVM view-models.
DomainUse-cases and entities — pure business logic.
DataRepositories, DTOs and mappers.
InfrastructureREST clients, local DB, device APIs.
Framework-independent business logicHigh testability at every layerPredictable, low-risk change

MVVM Presentation

Reactive view-models with unidirectional flow

The presentation layer uses MVVM so UI state is derived, observable and testable. View-models expose immutable state and intent handlers; views stay dumb and declarative.

ViewDeclarative, stateless React Native components.
ViewModelObservable state + intent handlers.
ModelDomain entities surfaced to the UI.
Testable UI logicClear state ownershipReusable view-models

Repository Pattern

A single source of truth abstracting data origin

Repositories hide whether data comes from the network or local cache. The domain asks for data; the repository decides how to fetch, cache, reconcile and return it.

RepositoryCoordinates remote + local sources.
RemoteRTK Query / REST API layer.
LocalSQLite / secure storage cache.
Swappable data sourcesCentralized cachingOffline-friendly

Offline-First Sync

Lossless capture and idempotent synchronization

Field apps assume the network is optional. Data is captured locally first, queued, and synced with idempotent, conflict-aware operations when connectivity returns.

Local WriteImmediate persistence to SQLite.
Sync QueueDurable, ordered operation log.
ReconciliationIdempotent server sync + conflict rules.
Works with zero connectivityNo data lossDeterministic sync

State Management

Redux Toolkit + RTK Query

Predictable global state with Redux Toolkit; server state and caching handled by RTK Query. Normalized entities, memoized selectors and optimistic updates keep the UI fast and consistent.

StoreRedux Toolkit slices + middleware.
Server StateRTK Query endpoints, caching, invalidation.
SelectorsMemoized derived state.
Single source of truthAutomatic cachingOptimistic UX

CI/CD & Release Pipeline

From commit to store, automated

A release pipeline that lints, type-checks, tests and builds signed artifacts, then ships to App Store and Play Store with staged rollouts and monitored releases.

IntegrateLint, type-check, unit tests on every PR.
BuildSigned iOS + Android artifacts.
ReleaseStaged rollout to App Store / Play Store.
MonitorCrash and performance monitoring.
