There’s a lot of ideas out there, but most of them are really too large of a system to turn into reality, especially with the time constraint we have of 3 months.
Any ideas/advice is appreciated. Thanks!

There are 4 other projects, but here are 2 to get you started.
Recently for a coding interview, I was asked to create a donation page. You could create something similar, however, you could also attach it to a persistent database that holds all the transaction amounts.
Very simple and straightforward
A good project to start is a cms, you’ll learn almost the most needed things in the process and it really helps you.
