Development of a beauty web app for mobiles

I need to create a Conference Poll website. Imagine I am presenting at a conference and I want to poll if the users are happy today. I need 2 websites: 1. Attendees use their mobile to access a url. They are presented with the question and some buttons as options 2. The presenter show graphs on the big screen plotting the responses For example: People enters the conference and they enter an url with their mobiles Everybody gets: How are you feeling today? and 2 buttons: Good or Bad In the big screen there is a pie chart (or something else) showing how many pushed good and bad in "real time" I will use as an example in a presentations (not for production, so no unittest or other production-ready tool/techniques. Also code quality is not priority) The work is mostly front-end and using ASP .NetCore MVC as a backend (I can give you most (or all) of the backend code) Questions can be hard coded in a database, no need of questions-management ui I need the work being done fast and very beautiful so I will not complain on the code quality :) The solution must run on Azure (I can do that part for you, no worries) Thanks!
