Senior React Native Developer for Cross Platform Mobile App Project

We are looking for a highly experienced React Native Developer who can take full ownership of building a modern, reliable and user friendly mobile application for both Android and iOS. The ideal candidate understands the realities of mobile production such as performance bottlenecks, navigation complexity, device compatibility, error handling, clean architecture and stable API communication.

You will work directly with our product team, UI designers and backend developers to translate requirements into functional mobile screens, reusable components and efficient data flows. The app must feel smooth on low and high end devices, load quickly, handle poor network conditions gracefully and follow modern UI and UX standards.

The project involves creating user flows, integrating REST APIs, storing data locally, handling authentication, setting up push notifications, managing permissions and preparing the app for release on both Play Store and App Store. You should be comfortable writing TypeScript, managing global state, structuring project files and maintaining consistent code quality.

We are looking for someone who understands how to solve real world problems, avoids over engineering, communicates clearly, meets deadlines and produces code that can be maintained long term. If you have delivered polished React Native apps before and can explain your approach to architecture and performance, this project will be a strong match.

✅ DETAILED TECHNICAL BREAKDOWN

Core Competencies

Your development style should follow a predictable folder structure, minimal repeated logic, reusable UI components and efficient rendering strategies. Every screen should load quickly and interactions should feel smooth throughout the app.

Technical Workflow

Set up project with TypeScript and proper folder architecture

Build UI screens based on finalized Figma designs

Connect API services with clean error handling

Prepare production builds with optimized bundle sizes

Best Practices

Use memoization for reducing re renders

Store tokens securely

Follow consistent naming and structure

Log important events for debugging

Use environment variables for API endpoints

Simple Code Example

const loadUser = async token => {

  try {

    const response = await axios.get(baseUrl + userInfo, {

      headers: { Authorization: "Bearer " + token }

    })

    return response.data

  } catch (error) {

    console.log("User load failed", error)

    return null

  }

}
