Good day,
I have experience in IoT, Web and Cloud systems like as Wine Chiller (Raspberry Pi Zero W) with IBM Watson and Node-RED integration, electrocardiograph (ESP32) with AWS integration, weather station (ESP866) with own API integration and many others.
Also I have experience with ESP8266, Arduino, SonOFF, Wemos integration to AWS via MQTT, with custom firmware and Tasmota, Mongoose third-party firmware.
About your project - I have experience in IoT dashboards with NodeJS, React, AWS, MySQL, MQTT. I can share some results of my work via private chat.
With best regards,
Ivan Medvedev.
