Web Developer Required for Meta-Software Development

Hello, We have an existing web application that runs in Google Cloud. It's effectively a Cloud-Management Portal for Raspberry Pi's. Currently, the GUI works, but requires updating to a modern, slick standard. This will require working with our existing Full-Stack Developer to migrate the existing HTML/PHP Files to the new appropriate setup. We require this to be setup it what we would call Meta-Software... Currently it's been setup in a 'proprietary' way so the next developer (you) has first to understand the way of coding of our current setup. If you use metasoftware, this phase will be skipped, because the metasoftware does it. Like an insert: you don't want to write this coding every time again. Just click "insert", select the fields, and done. Like a template. We need it to be crisp, slick, modern and professional. I am not looking for amateurs - I need real professionals who can take the reigns and get this sorted QUICK. I cannot work with someone who works part time or alike - we are trying to achieve a quick turn around on this. There could be future work for the correct candidate. You MUST complete the following task when applying: ******************************************************** To demonstrate your skills, please observe the attached 2 pictures which are screenshots of 2 pages. I want you to produce an example of how you would modernize this GUI. You do not need to make it functional, but a HTML file that shows your idea demonstrates your ideas, your skill set and helps us select the right candidate.
