How to keep a portfolio for a beginner?

Question

Career in IT

I am a beginner programmer, I have been developing in Android development for the last two years. And I decided to start a portfolio.

That's what interests me - what kind of projects to do for him. It is clear that those that show your skills, but what level? Make one or two big projects, which will take one or two years to write, where you will apply everything you can: databases, servers, android development, and so on. Or make 10-15 programs, in each of which you will apply one or two skills: in one - databases, in the other - backend, and so on. Or maybe there is some intermediate option?

And about the apps themselves - should they be "ideas in a million" or the most overused ideas that show your strictly technical skills?

Answer 1

You can work on one project for a long time, and not many, that I can do this and this, etc. If I were you, I would post one project (depending on what you want to do) and work on it, improve it / modernize it. To see the whole spectrum in one project, and not in many.

Answer 2

databases, servers, android development, etc. Or make 10-15 programs, in each of which you will apply one or two skills: in one - databases, in the other - backend, and so on. Or maybe there is some intermediate option?

I wonder how you have a backend in one program, and databases in another?
Why can't you make simple little projects that will include databases, a backend and an android client?
Well, in general, a portfolio of YOUR projects is made from their own projects. When you have your own hobby, participation in open source. For my own interest, and not solely for the portfolio.
