What projects to fill the portfolio?

Question

Android

Hello, I'm a mobile developer with some freelancing and project experience. I wonder what projects can be filled in the portfolio - necessarily original ideas that are not on the market, or maybe, for example, an alarm clock or a notebook with open source and just good execution?

Answer 1

original ideas that are not on the market

You are not a creative, you are a developer. The client will hire you in order for you to qualitatively implement his idea. Here's what's done well.

Answer 2

At first, any for quantity. Over time, when there will be a lot of projects, you will choose only iconic ones.

Answer 3

All the works that you consider the best.
