Senior React Native Developer (Freelance / Contract)

We're kicking off a greenfield project for a UK-based company in the events and healthcare space. The goal is to build a cross-platform mobile application that will serve as an extension of their existing WordPress-based system.

The mobile app will present key content and data to users in a read-only manner, pulling from the current CMS via API. Additionally, the app will connect to a lightweight auxiliary backend that will support a new user role and limited functionality. The solution will be built using React Native to maximize code reusability across iOS and Android within a limited budget.
What You'll Do

• Lead the estimation of effort, scope, and timeline
• Work closely with a business analyst to clarify functional and technical requirements
• Design and develop the mobile application using React Native
• Integrate the app with the existing WordPress system (read-only)
• Connect with a custom auxiliary backend
• Ensure a smooth, performant, and user-friendly experience
• Optionally lead a small team during the development phase

Requirements

• 4+ years of experience in mobile development
• Strong hands-on experience with React Native and JavaScript/TypeScript
• Proven experience delivering cross-platform mobile apps
• Familiarity with RESTful API integration
• Understanding of native mobile capabilities (e.g., push notifications, offline support)
• Strong communication skills and ability to work independently
• Fluent in English (written and spoken)

Nice to Have

• Experience with WordPress REST API
• Familiarity with lightweight backends (e.g., Firebase or custom Node.js APIs)
• Experience in leading or mentoring other developers

Compensation

Please include your hourly or daily rate in your response. We're open to negotiation depending on your experience and availability.
