Okay, I understood your point. Let me introduce my vision of it.
At first, I think we can follow the principle of IID ( Iterative and Incremental Development ) and organise the whole development process of website by some circles.
The short description of architector: we can use github pages for avoiding server side and hostings. We can develop a very simple, but at the same time a modern single page application by using, for example, the latest version of React.
The circles of development:
( NOTE ::: All steps of development in my suggestion will be related to React js and its adjacent tools. Of course, it's just my suggestion, we can change it ).
Circle 1) At first we need an organisation in github and repo for website.
Circle 2) We can create a simple SPA in React with content of "Coming soon" and integrate it with github pages.
Circle 3) Integration of Material-UI, React-router and sample date base based on .json file.
Circle 4) After that we can create proper UI components for showing members and projects from sample db file.
Circle 5) And integration of it with Firebase.
I tried to combine all possible steps with this 5, in real there are more than 5. It's just for forming an idea.
