Hello,
I assume your backend is running and expose json data via api, I suggest that you will create a web app via nodejs and angularjs. Your app will interaction via ajax/services call.
The web app will make call to your backend's apis and generate data, html based on designed frontend. All you need is let me know the apis documentation (what url, data format, validation ...) and send html/css code of frontend.
I would be happy to set up a webapp and integrate your code.
Please let me know if you need more information.
Thank you
