I'm a completely self-taught software engineer aiming to get a full-time role as an Android engineer. I have no published apps in Google Play at the moment; I'm currently working on a metronome app as I am a musician.
What kind of fundamentals should I know to feel confident, specifically confident enough to apply to jobs? It’s hard for me to feel confident from a non-traditional Computer Science background. I keep doing more and more tutorials and courses to build up my confidence, and it just goes on and on. Is there some roadmap I can follow?
