Need a freelancer for system design and consulting

#IoT
Our company develops wireless sensors for vehicles to monitor tire parameters. We have a junior Fullstack programmer on the team to handle the incoming data streams.

Our project may take 1 month and consists of two parts:
(1) Collect the data from the sensors using the company's hardware device or simple mobile app and upload it to the cloud.
(2) Update our database and make it ready for data analysis purposes.

There are already APIs for the system and a simple DB on AWS EC2.
Neet to guide and mentor our programmer.
Need to be hands-on on the project.
