What We Build

Complete React Native Services

From new apps to migration and performance engineering — we deliver React Native solutions end-to-end.

Full-Cycle Development

End-to-end React Native apps with clean architecture, TypeScript, state management, and native performance for iOS and Android.

Expo & Bare Workflow

Rapid development with Expo managed workflow or bare workflow for full native control — EAS Build, OTA updates, and config plugins.

Migration & Brownfield

Migrate native apps to React Native or integrate RN modules into existing codebases with incremental adoption strategies.

React Native for Web

Extend your mobile app to the web with React Native Web — shared codebase for mobile and browser experiences.

Performance Engineering

Hermes optimization, bundle analysis, memory profiling, and animation tuning for smooth 60fps experiences.

Team Augmentation

Dedicated React Native developers integrated into your team — fractional, full-time, or project-based engagements.

FAQ

Frequently Asked Questions

Quick answers about React Native, Expo, native modules, and timelines.

React Native uses JavaScript and the native rendering engine, while Flutter uses Dart and its own rendering layer. RN is better if your team knows JavaScript/React and you need deep native integration. Flutter is better for custom UI and pixel-perfect animations. Both deliver excellent cross-platform performance.
Expo is ideal for most projects — it provides managed workflow, OTA updates, EAS Build, and hundreds of compatible modules. Use bare workflow only when you need custom native code not supported by Expo's config plugins. We'll recommend the best approach for your use case.
Native modules are needed when you require platform-specific APIs not available in the React Native ecosystem — such as custom Bluetooth protocols, NFC, advanced camera features, or proprietary SDKs. We build and maintain custom modules with full TypeScript bindings.
OTA (Over-The-Air) updates via CodePush or EAS Update allow you to push JavaScript bundle updates directly to users without going through the app store review process. Native changes still require a new build, but most JS/UI updates can be delivered instantly.
A typical React Native app takes 8–14 weeks from discovery to launch. Simple MVPs can be delivered in 4–6 weeks, while complex apps with extensive native integrations may take 16–20 weeks. We provide a detailed milestone-based timeline after discovery.
