Adding Firebase ESP8266 code to my existing ESP32 MQTT code

Job ID: 33987233

Budget: $10 – $30 USD

I have a functional ESP32 MQTT code and would like to add another functional ESP8266 code. Both codes suppose to work at the same time. A previous developer did this task but neither MQTT or firebase NOT working, maybe they in conflict or something else?
