Hello Sir / Madam,
I could go trough your task description and Its understandable.
As I understood, you already have a set of Web APIs or Web Services that can be used to retrieve some IOT data. Now you want to get developed a good looking front end to visualize those IOT data on a web app or website.
I'm very confidant to say that Its doable. I can develop a very attractive and responsive front-end using HTML5, CSS3, JavaScript, Node.JS, Angular, React.JS, jQuery and Bootstrap.
I have already developed a complete front-end and back-end for an executive dashboard for banking professionals in US banks. I used HTML, CSS, JavaScript, Node.JS, Angular, and Bootstrap for it. It was included with graphical visualizations like charts and table views also. I can develop nice front end for you as your expectations with my previous knowledge and experience.
I'm a software engineer having 15+ years of experience in many different technologies.
Please contact to me for further discussions.
Regard,
Lasantha
