What We Build

Comprehensive React Native Engineering

01

Shared Javascript/TypeScript Codebase

Designing and building cross-platform applications using React and TypeScript, maximizing code reuse between iOS and Android.

02

Native UI Component Mapping

Utilizing React Native's core layout model to render native UI components directly, ensuring platforms look and feel familiar to native guidelines.

03

Custom Native Modules & Turbomodules

Writing custom Kotlin and Swift native extensions (bridges) to interface with local hardware sensors, platform features, or proprietary SDKs.

04

Performance Optimization (Hermes)

Tuning application execution using Meta's Hermes JS engine, minimizing app startup times, memory footprint, and optimizing JS thread execution.

05

Predictable State Architecture

Implementing clean, modular state solutions (Zustand, Redux Toolkit, or Recoil) to manage application flow without causing redundant re-renders.

06

Seamless OTA (Over-the-Air) Updates

Integrating Microsoft CodePush to deploy critical bug fixes and content updates directly to users instantly, bypassing App Store review loops.

The Challenge

Cross-platform shouldn't feel like a compromise. Your users deserve native performance.

Reusing code between web and mobile is a major productivity booster, but building with React Native is not as simple as porting a website. Poorly configured native bridges, heavy JS threads, and unoptimized rendering loops can lead to frame drops during scrolling, sluggish navigation, and memory leaks. To get native-grade performance out of React Native, you need engineers who understand the underlying mobile architectures, how to utilize the Hermes engine, and when to write custom Native Modules. Quecko builds React Native apps with strict performance modeling, lightweight state management, and optimized native integrations. We deliver cross-platform apps that run as fast as they look.

How We Collaborate

Dedicated React Native Pod

Full-time React Native developers, QA testers, and designers working to build and scale your cross-platform application.

Project-Based Build

End-to-end development of your application from layout wireframing to dual App Store launches.

Bridge and Performance Audit

Technical review of existing React Native apps to optimize slow rendering, bridge overhead, or build custom native adapters.

FAQ

Frequently Asked Questions

Yes. While the UI components are different (e.g., `<View>` vs. `<div>`), we can structure your project to share business logic, API helpers, helper utilities, and state management hooks (via monorepos).

Expo is a robust suite of tools that simplifies React Native development. It automates build processes, handles push notification infrastructure, and enables Expo Application Services (EAS) for fast cross-platform deployment. We utilize Expo where appropriate for rapid iteration.

By integrating tools like Microsoft CodePush, we compile and upload JavaScript/TypeScript bundles directly to a cloud server. When the app opens, it checks for updates and downloads the new bundle silently, updating the UI immediately without requiring a full App Store review.

React Native is not ideal for graphic-intensive 3D applications, apps requiring real-time heavy CPU computation (like complex audio/video editing engines), or projects requiring extensive custom OS background services.
