Hello, I am looking for an experienced developer or development team to create a professional desktop application for an IoT monitoring system similar in functionality to solutions provided by Aeroqual. Currently, I have a desktop software application that receives sensor data via USB (serial communication), displays the values in real time, plots graphs, and saves the data into Excel files. The new system will extend this functionality by adding wireless data transmission using GSM and MQTT, while also preserving the existing wired communication capability.
The application must therefore support both communication modes: wired (USB/Serial) and wireless (GSM → MQTT). In the new architecture, remote sensor devices will transmit environmental data through GSM/GPRS/LTE networks to an MQTT broker. The desktop application must connect to this broker, subscribe to device topics, receive the incoming data in real time, and display it in a clear and user-friendly interface. At the same time, it must also continue to support direct wired data acquisition from locally connected devices via USB.
The application should provide real-time visualization of measurements from multiple devices simultaneously, regardless of whether the data source is wired or wireless. It must display current values, device status (online/offline), timestamps, and dynamic graphs with zooming and historical viewing capabilities. The software should support handling a large number of devices and continuous data streams without performance issues.
In addition to visualization, the application must store incoming data locally and allow exporting the data to Excel files for selected devices and time ranges. It must also allow saving graphs and reports as image files (PNG or JPEG) in high resolution.
A secure multi-user login system is required. The system should support thousands of different users with role-based access levels such as administrator, operator, and viewer. Proper authentication, password protection, and session management must be implemented.
The application must be designed as a robust desktop solution (primarily for Windows), capable of handling thousands of devices and users efficiently. It should include configuration options for MQTT connection parameters such as broker address, port, credentials, TLS settings, and topic structure, as well as configuration for serial communication parameters (COM port, baud rate, etc.). Automatic reconnection and error handling for both network interruptions and wired communication failures are required.
Additionally, the freelancer will be expected to assist with the integration of GSM devices with the MQTT infrastructure, including guidance on data transmission, topic structure, and overall system architecture to ensure reliable end-to-end communication from remote devices to the desktop application.
The developer is expected to deliver the complete source code, compiled installation package, and documentation for setup and deployment. Please include in your proposal your suggested technology stack, relevant experience with IoT and MQTT systems, examples of similar projects, estimated development timeline, and cost. I am looking for a reliable long-term solution developed according to professional software engineering standards.
Contract duration of less than 1 month, with 30 hours per week.
Mandatory skills: C++, MQTT, Embedded Linux, Embedded C, NFC, Arduino, PCB Design, Real-Time Operating System, Qt Framework, Firmware Programming, ARM Cortex-M, Robotics, FreeRTOS, Altium Designer, RFID.
