IoT Mobile App Development (Flutter / React Native) with BLE, MQTT & Real-Time Device Integration

We are developing an IoT mobile application platform that connects smart devices with mobile applications in real time. We need a mobile + IoT engineering team to build a scalable cross-platform solution for device monitoring, control, and data synchronization. Project includes: Mobile application development (Flutter or React Native preferred) IoT device integration via Bluetooth Low Energy (BLE) MQTT-based communication for real-time IoT data streaming REST API integration for cloud backend services Device pairing, authentication, and secure communication flow Real-time dashboard for device status and telemetry data Scalable architecture for multiple connected devices Technical requirements: Strong experience in mobile app development (Flutter / React Native / iOS / Android) IoT systems integration (BLE, MQTT, smart devices, embedded communication) Real-time data synchronization and event-driven architecture API integration (REST / WebSocket) Experience with IoT platforms or connected device ecosystems We are looking for a team that has experience building production-level IoT + mobile systems with real-time data flows.
