IOT Development using esp32 module to control I/O Device for No/Off Function via BLE(Bluetooth)

We are seeking an experienced IoT, IOS/Andriod App/Cloud database system developers, to action the following project

Your main task will involve:
1. Connect to a Expressif ESP32-Wroom device via BLE (Bluetooth) to turn attached device on/off.
2. Have a developed IOS/Android Application to communicate to the BLE to send On or OFF Command
3. The Mobile Application will be required to connect to a Cloud based Database to validate permissions for users account before the mobile device can send the request to the module to turn on/off function.
4. Integration to existing software systems to send update to database for account permissions to be assigned. This can be done via API to 2 platforms.


Your main task will involve:

- Developing and implementing an Arduino-based automation control system suitable for an industrial environment.

Skills and Experience Required:
- Robust experience with Arduino platforms;
- Extensive knowledge and demonstrable experience in IoT development;
- Expertise in implementing automation control, preferably in an industrial setting;
- Problem-solving skills and ability to work independently.

This project offers the chance to engage with specialized technology and contribute to the growth of industrial IoT applications. Therefore, any examples of past equivalent projects will be highly advantageous.
