I will develop a reliable cross-platform mobile application for Android and iOS using React Native, Expo and TypeScript, with an optional Node.js and Express backend.

What I can build:

• Custom Android and iOS applications • Responsive mobile screens from Figma or your design • Authentication and secure user sessions • REST API development and integration • MongoDB or SQL database integration • GPS and background-location tracking • Push notifications and real-time communication • QR code and camera functionality • Offline data storage and synchronization • Admin dashboards using React.js • Bug fixing and performance optimization

My experience includes enterprise management platforms, field-service applications, GPS attendance systems, inventory workflows, real-time chat and offline-first mobile applications.

You will receive clean, maintainable source code, regular progress updates, testing and setup documentation.
