Canvas module in Web interface

We are looking for web app programmer who is able to do module: - canvas function for the web interface - uploading graphic plans (e.g. floors, so every floor is a different file) - possiblity to place points on those plans (e.g. arrangement of devices in parts of the building) - possibility to choose plans (e.g. Floor 1, Floor 2 , Floor 3 etc. and specific devices assigned only to them) - view of all plans (e.g. floors) - possibility to delete plans (floors) - points (devices) parameters from base (input data: Websocket, json) - color signaling the status of points (f.e. state1 – green, state2 – red, state3 – blinking yellow etc…) In the attachments I have included an interface of our website prepared for the function described above. In a private conversation, we can share a link to our website.
