Senior React Native Developer for Cross Platform Mobile App Development

We are seeking an experienced React Native Developer who can build a high quality, cross platform mobile application with clean architecture, strong performance, intuitive UI, and reliable API integration. This project requires someone with a proven track record of delivering production ready apps for both Android and iOS using modern React Native standards, TypeScript, and industry best practices.

You will work closely with our design team, backend developers, and project management to turn our feature requirements into a polished mobile experience. The goal is to deliver a stable, responsive app with smooth navigation, optimized rendering, and minimal performance overhead. We expect proactive communication, technical clarity, and the ability to solve problems independently.

This project involves building modular UI components, setting up global state management, integrating REST APIs, configuring push notifications, handling device permissions, and preparing the app for App Store and Google Play submission. Strong knowledge of React Native latest versions, navigation frameworks, async data handling, and error tracking tools will be essential.

We value developers who write clean code, follow consistent patterns, understand mobile UX principles, and test thoroughly before delivering. If you understand the challenges of real world app development such as memory leaks, slow renders, offline handling, edge case testing, and platform differences, then you are exactly who we are looking for.
