Hi, this project looks interesting, I'm eager to contribute.

This issue presents itself as a nice starting point into your codebase, mind if take it?

welcome! We're always happy to have new people contribute. You're more than welcome to pick up issues. The code might be a little hard to grasp maybe because there is a lot going on, but most of the sonarcloud issues are doable enough.

Pretty nice work done! We got rid of half the code smell issues

I leave this issue open for now, so we can tackle the rest later
