Flutter Mobile App Development for Iot Sensor (Ios & Android)

We are seeking an experienced Flutter developer to build a mobile application for both iOS and Android platforms. This innovative app will serve as the mobile interface for our custom BLE sensor, designed for traditional musicians. The core functionality of the app involves receiving and visualizing real-time data (pressure, temperature, and humidity) from the BLE sensor, presenting it through a fluid, interactive live data dashboard.

The project requires robust user authentication integrated with our existing API. The app's architecture must be designed to support multi-language (i18n) capabilities from the outset, ensuring a global reach for our users. We are looking for a freelancer with a strong understanding of mobile development best practices, real-time data handling, and API integration to deliver a high-quality, performant, and intuitive application.
