Greetings, I am an electrical engineer with several years of experience on embedded systems and IoT, and I have been working with MQTT, HTTP and other protocols commonly used on IoT devices, and I have been developing firmware and software on the following platforms: AVR; PIC; 8051; STM32; ESP32 / ESP8266; Raspberry PI; Desktop (Windows and Linux); Mobile. Besides that, I am a rapid learner, so developing for other platforms or using other technologies will not be a problem. I will be waiting for your contact so we can discuss better all the details. Kind regards.
