How Do You Showcase Non-Visual Work - Scripts, Backend

[#1]

Hi, I wonder what strategy do you use to show your clients how ingenious and secure your database solution is or how smart your Discord Bot can be?

I focus more on stuff that is hard to visually represent. A Discord bot that interacts with APIs, downloads and parses database for you, communicates in human-lik language --- but I can't put the conversations or even profile pics in the preview picture...

Still, its easier than stuffing it with other backend stuff which would be just --- code. Fire charts could look right, perhaps?
