I'm finally in the process of learning Angular and the best way for me to really retain the information is through a project. So I racked my mind for a short while and eventually settled on what might be a pretty decent idea which if executed and scaled properly could be monetized well. It's real estate related and targeted sort of towards the average person. I don't want to give too much away but it goes to show that if you're looking for project ideas stay in your wheelhouse and focus on things or problems that interest you.
