Hello,
I am an engineer and I can help you. I can even build you a prototype of what you want before you hire me : from the screenshots of the output I will provide you, if you are satisfied you can hire me, if not you can still hire another freelancer.
To better help you, I would need an example of the json data you will use, for testing.
I am available immediately and this can be done within a day. I hope we can work together.
Best regards
