Project ideas wanted

Hello fellow devs

I am a full stack developer in learning.
I am looking for an idea for a great project to work on to display my current coding abilities, while expanding on them during the project.

I have read many articles and watched videos relating to suggested projects, but I would like to hear from this community, what has been, in your experience, a project worth sinking your teeth into, while being something meaningful to show to prospective clients/employers.

Any advice would be greatly appreciated.
