Digital Signage Webpage for Live Sign-In Display

I am looking for a skilled web developer to create a modern, real-time digital signage webpage that displays live sign-in data from our Sign In App system. The webpage will be shown on a digital signage screen and should automatically update when users sign in or out.

Key Features:
Live Updates – The webpage should automatically refresh and display real-time sign-in data without needing manual intervention.

API Integration – Connect to the Sign In App API to fetch and display sign-in data. API docs: Sign In App API.

Grouped Display – Show signed-in users by group, including their name and the time they signed in.

Modern & Clean UI – The design should be sleek and professional, using the Raleway font for a polished look.

Error Handling – Display a clear message if the connection is lost or if there are general API errors.

Full-Screen & Responsive – The page should be optimized for digital signage, ensuring clear readability on large screens.

It should be easily to upload to a standard web hosting account.

If you have experience in API integrations, real-time web apps, and modern UI design, I’d love to hear from you! Please provide examples of relevant projects you've worked on.
