As a junior developer I'm always afraid using any AWS service to make a mistake that cost me a lot of money. I'm not talking about millions, simply 2k would be really bad for me.

That's not the main purpose. Make the project open source will help me in a future job application. In my country (Spain), companys value more your personal projects than whatever you made in your four years of college.
The app will be part of my final college project so, badly or well I will have to do it. However, the app may not be used by the organization, but I want to produce an useful app in case they want to use it.
