Hello, I am an experienced IoT developer. My tech stack includes Wi-Fi, BLE, Web sockets, MQTT, TCP/IP, UDP/IP, HTTP, Javascript, HTML/CSS, REST APIs, NodeJS, MongoDB, React Native, RS232, SPI, I2C, Canbus etc. I am proficient un using various microcontrollers including ESP32's series, Arduino based microcontrollers such as Teensy, Nano, etc. In one of my projects, I have implemented MQTT protocol to send the data from esp32 to the mobile app and vice versa. The mobile app have turn on/off buttons and sliders. The sliders are used to set the PWM duty cycles and temperature threshold value. The esp32 receives the command and setting values and sends the sensor values to the mobile app via MQTT. I am willing to work with you and for that I am ready to have meetings with you. Looking forward to have a nice conversation with you. Best Regards, Azhar
