I Learned React now I need practice

Hi, I am a new developer (the new guy) and I just learned react and redux. and of course to really get good at something (especially codding) it is essential to do a lot of practice and i have built more todos and cart than React tutorials on youtube, it's now borring***.

I need something more challenging, hopefully including Redux and React-Router.

I just need some kind of list of cool stuff to build.

Thanks a lot.
