Cross-Platform (Flutter / React Native)

One codebase, two platforms. I build cross-platform mobile apps using Flutter or React Native that deliver native-quality UX, performance, and store readiness. Whether you're shipping an MVP quickly or maintaining feature parity across iOS and Android, cross-platform development reduces costs and timelines by 40-60%.

My approach balances code reuse with platform-specific polish. I implement native navigation patterns, platform conventions (iOS HIG, Material Design), and custom native modules where needed for camera, permissions, or third-party SDKs.

What I Deliver

Flutter or React Native builds with 80-95% shared code
Platform-specific UI polish (iOS/Android conventions)
Offline-first with local storage & sync
Push notifications, deep links, universal links
Native modules for platform-specific features
CI/CD pipelines (TestFlight, Google Play)
App Store/Play Store prep & launch support

Best For

MVPs with tight timelines (4-8 weeks)
Feature teams needing iOS/Android parity
Budget-conscious projects (40-60% cost reduction)
Web + mobile with shared logic (React Native)
High-performance UIs (Flutter)
Existing Flutter/React Native app improvements

Flutter vs React Native: Decision Matrix

Factor	Flutter	React Native
Performance	Excellent (compiled to native)	Very good (JavaScript bridge)
UI Flexibility	Highly customizable widgets	Native components + custom
Language	Dart (easy to learn)	JavaScript/TypeScript
Web Support	Beta (improving)	React shared code (excellent)
Third-Party Libs	Growing ecosystem	Mature, extensive npm packages
Hot Reload	Sub-second	Fast (with Fast Refresh)
Best For	Custom animations, design systems	JS teams, web code sharing

My Recommendation: Choose Flutter for high-performance UIs and custom animations. Choose React Native if your team knows JavaScript/React or needs web code sharing. Both deliver native-quality apps.

Implementation Approach

1. Architecture Setup

Flutter: BLoC or Riverpod for state management, repository pattern for data layer.React Native: Redux/MobX or Context API, React Navigation for routing.

2. Platform-Specific Modules

Create native bridges for camera, biometrics, health data, or third-party SDKs. Implement platform channels (Flutter) or native modules (React Native) with proper error handling and fallbacks.

3. UI Polish

Follow iOS Human Interface Guidelines and Material Design. Use platform-specific fonts (SF Pro on iOS, Roboto on Android), navigation patterns (tab bars vs bottom nav), and interaction conventions.

4. CI/CD Pipeline

Automate builds with Fastlane, GitHub Actions, or Bitrise. Set up TestFlight/Play Console beta distribution, automated screenshot generation, and release notes.

Tech Stack

Flutter Stack

Dart 3.0+, Flutter 3.16+
BLoC, Riverpod, Provider
Dio for HTTP, sqflite for local DB
Firebase (Auth, Analytics, Crashlytics)

Typical Outcomes

40-60% faster delivery vs building separate native apps
80-95% shared code between iOS and Android
Native performance: 60fps animations, fast startup, smooth scrolling
Reduced maintenance: Single codebase for features, bugs, updates
Store-ready in 4-8 weeks for MVPs

Frequently Asked Questions

Flutter vs React Native: which should I choose?

Choose Flutter for high-performance UIs, custom animations, and if your team knows Dart. Choose React Native if your team knows JavaScript/React, needs extensive third-party integrations, or wants easier web code sharing. Both deliver native-quality apps.

How much code can I share between iOS and Android?

Typically 80-95% shared code. Platform-specific modules (camera, permissions, native integrations) require separate implementations. Flutter's widget library and React Native's component system handle UI differences automatically.

Can cross-platform apps feel truly native?

Yes—with proper platform conventions (iOS Human Interface Guidelines, Material Design on Android), native navigation patterns, platform-specific fonts, and custom native modules where needed. Both Flutter and React Native can deliver indistinguishable native experiences.
