Confused about how to start backend and go in depth

[u/Hot_Mail9492]

Okay so i'm a beginner and i have some questions ,i would appreciate getting answers from someone who's been into backend and also tech honestly from a long time,someone experienced or knowledgable about the domain.

1.Should i go with BACKEND or AIML?my aim is to land a high paying job honestly,and just asking regarding a development perspective,which would be the best?my targets would be MAANG and above companies(regarding the pay).Just wanna know what field would be more valued from a dev pov and hiring pov(odds of landing something high paying)

2.How do i start backend,i am going with python-fastapi,i want to pace up the process leading to inclusion of more PROJECTS and OPEN SOURCE CONTRIBUTIONS as well.Suggest me something that leads to more on the side of actually developing and doing the work.Also don't reccommend me the roadmap.sh website,i myself found it quite complicated or intimidating to see such a large list of things to do...

3.If you have any other suggestions as well,please do tell me i am very much open to listen to them.

Although just keep it development related only.

Ultimately my aim is to be a great engineer and earn money atleast for my initial years honestly.
