Mentoring wanted on my first project

Hello,

I wanted to make my first website with rust.
I have made a website where I ask the Rijksmueaum for some data and display some paintings.

Then I placed all the paintings in a database which costs me some3 hours so I had a idea to make it work "better".

What I thougth was make some sort of cache where the code is looking if the url where the image of a painting is shown is looked up, When it in the cache use that, if not there ask the api for the url and put it into the cache.

Now Ilike have some free mentoring how I can make this work in rust with tests of course.
