"You can only become a great developer by putting the effort in. Imagine for a moment — You can’t become fit physically by reading a lot about fitness. You actually need to go to the gym and put the hours and sweat in! Same concept applies for coding as well.

Here are 8 fantastic projects to train your coding muscles! The goal is to build each app with whatever technology stack you prefer. Keep it conflict free, use whatever you want!
