As an electronic engineer I have experience in embedded systems design.
In particular, at curricula we have a course in raspberry pi development.
Nowadays, I'm doing a fullstack developper course in order to improve my IoT skills.
What you are asking for is a good chance to increase my reputation here at Freelancer.com
Also, I have a raspberry pi that can be connected to internet 24/7 in order to let you see the implementation.
Hope we can chat for further details.
Sincerely yours,
Marcos.
