I've been doing web development for about a year now, but I've definitely focused on front-end stuff during that time. This is mostly because I've found it to be a little easier to start and finish my ideas.
I've been wanting to do more back-end work but I typically have a difficult time thinking of simple, useful, and interesting ideas that I can finish. Most of what I've come up with revolve around building some API, which is something I definitely want to do but I'm not always sure about where to start.
I'd love to know if there are other fun or interesting ways to get into back-end programming. It would ideally provide a useful learning experience for someone who has conceptual knowledge but no practical experience with server-side development. The ideas don't have to be restricted to a specific language or technology, but I've been interested in using the following if it helps:
Looking forward to seeing your ideas. Thanks!
