JS decoder for Sensor on Helium Network

Job ID: 34475582

Budget: $30 – $250 CAD

I am looking for someone to code me a java Script decoder for a LoRaWan sensor. The sensor is providing payload in base64 and I need someone to extract the data in helium to send the data to datacake and show it.
The supplier has provided me with a decoder but that does not work under the Helium cloud server.
