Expert React Native Development | BirajTech

Build Your iOS & Android App 47% Faster—Without Compromising Quality

You need a mobile app on both platforms, but building two native apps means double the cost, double the time, and twice the maintenance headaches. Your competitors are already shipping while you're still planning.

At BirajTech, we've spent 6 years mastering React Native development. We've helped 40+ businesses launch cross-platform apps that perform like native while cutting development time nearly in half.

What We Do

Full-Cycle React Native Development

We partner with you from concept to App Store approval. Our team ships production apps handling everything from real-time video streaming to financial transactions using React Native 0.73+.

Real Example: We built a healthcare appointment platform for a clinic network in 11 weeks—half the time native development would have taken. The app now serves 15,000+ monthly active users with 4.7+ star ratings on both stores.

Legacy App Modernization

We've successfully migrated 12 apps to React Native, including a logistics tracker stuck on outdated Cordova code. Result: 89% fewer crashes, 2.3x faster load times, and a maintainable single codebase.

Enterprise Integration

We connect React Native apps to complex backend systems—SAP, Salesforce, custom APIs, payment gateways, authentication providers, and more. All with proper error handling and offline-first architecture when needed.

Our Process: Proven Over 40+ Projects

Discovery & Architecture (1-2 weeks) Technical feasibility assessment, API planning, and realistic timeline—no optimistic guesswork.

Development Sprints (2-week cycles) Working builds delivered every sprint with:

  1. TypeScript for type safety
  2. Automated testing (Jest, Detox)
  3. Code review by senior developers
  4. Deployment to TestFlight and Google Play

Quality Assurance Three-layer testing: automated tests (80%+ coverage), 15+ real devices, and performance profiling. We test on older devices too—30-40% of users aren't on flagships.

Deployment & Support We handle App Store submissions and provide 90-day post-launch support with 48-hour SLA for critical bugs.

When React Native Works (And When It Doesn't)

Choose React Native For:

✓ Budget-conscious dual-platform apps - Save 60-70% vs two native apps ✓ Content-driven or business logic apps - Perfect for inventory systems, social networks, e-commerce, booking platforms ✓ Rapid iteration needs - Push updates without App Store review using CodePush ✓ Web developers entering mobile - Leverage existing React skills

Go Native Instead For:

✗ Heavy graphics or gaming (complex 3D) ✗ Extensive platform-specific features (60%+ native code negates benefits) ✗ Maximum performance requirements (video editing, real-time trading)

We're Honest: In 2023, we turned away a camera app project requiring real-time AR filters—React Native wasn't mature enough. They appreciated the honesty and returned for a different project.

Common Concerns Addressed

"Is React Native as fast as native?" For 90% of apps, users can't tell the difference. Our apps achieve sub-2-second launch times and 60fps navigation.

"Will I be locked into one vendor?" No. React Native is open-source with a huge community. We document thoroughly using best practices so you're never stuck.

"What about maintenance?" We offer maintenance plans from $800/month. One client's app we've maintained since 2020 still runs smoothly on iPhone 8 through iPhone 15
