What actually happens after you upload an image?

I built a tool to visualize what happens after you upload a file (queue, worker, logs).

Backend systems can feel pretty abstract when you're learning.

You hear about queues, workers, background jobs… but it’s hard to actually see what’s happening.

So I tried building a small interactive demo to make that visible.

You can:

upload an image (or use a demo)
and watch it go through a real backend flow
(API → queue → worker → processing → storage)

Here’s what it looks like:

It’s not just an animation, it runs real services and shows:
live logs
timing for each step
system state changes

Would love feedback.
You can try it here (takes ~5 seconds):
