React Native Development Company Building Fast, Production-Ready Mobile Apps
iOS and Android from one TypeScript codebase. React Native New Architecture (Fabric + Hermes) for near-native performance. AI integration, n8n backend automation, and App Store submission included — from a team that has built production apps since 2014.
React Native New Architecture — The Performance Gap Has Closed
The old bridge architecture that gave React Native a performance reputation is gone. Fabric renderer and Hermes engine deliver near-native performance on both iOS and Android. We have built on New Architecture since it was released — it is not an experiment for us.
Why React Native New Architecture Changes Everything About Cross-Platform
The new Fabric renderer and Hermes JavaScript engine eliminate the asynchronous bridge that caused the performance issues that gave React Native a bad reputation. Direct synchronous communication between JS and native modules. Concurrent rendering. Better startup time. Near-native performance on both platforms from one codebase at 40 to 60% of the cost of two separate native builds.
React Native New Architecture vs The Old Way
| Factor | Old Bridge Architecture | New Architecture (Fabric + Hermes) |
|---|---|---|
| Rendering | Asynchronous bridge, frame drops | Synchronous JSI, near-native frame rates |
| Startup time | Slow JS engine initialization | Hermes pre-compilation, faster cold start |
| Native modules | Async, potential latency | Synchronous JSI direct invocation |
| Concurrent rendering | Not supported | React 18 concurrent features supported |
| Expo support | Limited | Full Expo SDK support from SDK 50+ |
Our React Native Development Services
React Native New Architecture Apps
Production apps built on Fabric + Hermes from the start. No legacy bridge architecture, no technical debt. TypeScript strict mode, component architecture that scales, and performance budgets enforced in code review.
Expo and EAS Development
Expo SDK and EAS (Expo Application Services) for faster development cycles, over-the-air updates, and simplified App Store pipeline. We use Expo where it fits and eject when native capabilities require it.
AI Mobile Integration
Voice AI with streaming responses, LLM-powered chat interfaces, on-device ML with TensorFlow Lite and Core ML, and AI-assisted UX personalization. Most React Native agencies cannot offer this.
React Native Architecture Migration
Migrating existing apps from the old bridge architecture to New Architecture. Performance profiling, dependency audit, and migration plan before any code changes.
App Store and Google Play Submission
Store listings, screenshots, ASO keyword research, privacy nutrition labels, and submission handling. We manage the review process and handle rejections. Included on every project.
n8n Backend Automation
Automated push notifications, data sync triggers, behavioral workflows, and backend automation that extends your app without building a custom backend from scratch.
Real Results from Real Client Projects
Custom build — #1 rankings across the entire service area
The same engineering discipline we apply to every project. Clean architecture, semantic code, schema markup, and n8n automation for monitoring. One team, full ownership from architecture to production.
