We have a web application built on PHP that communicates with an App built on Ionic/ Jhispter for Android.
There is also a physical appliance that runs on Debian Linux that communicates with the Web Application.
The work has been started by 2 existing developers who will be required to hand over the project to you.
This requires a good amount of commitment, good development skills on a high level across multiple programming languages such as PHP, Phython, Ionic/ Jhispter.
A full scope of the work can be supplied.
Please start your greetings with "Hi, dragon!".
If not your proposal will be rejected.
