Ask HN: Do you have a project you can share that uses system design concepts?

Hello,

I'm learning about system design concepts. I suppose one way of understanding them better would be to implement them myself but seeing as how i don't have a service/web-app/anything with any real users, and i do not work in an area where these concepts can be applied, i am wondering if somebody would be interested in demo-ing their project that implements some of these system design concepts. It would help to see them in action.

Is it even possible for somebody to demo these concepts?

You can screen share and show as little code as possible.
