I learnt it bit by bit over the course of years, probably like many other Developers. Learning the basics in the very beginning will help you to (faster) identify, understand and solve many problems in the projects you will build. In this post I'll start with an overview.
For a few weeks I'm unemployed now and starting to build my own SaaS project. A very obvious change to my job last year is that I'm alone now and not solely responsible for coding anymore. Here some thoughts on what I think you should focus on and how to organize and juggle it all.
