Today I deeply understood/learned that if anything complex has to be built, tested and maintained by a single person the most important factor to don't go crazy is the concepts of "separation of concern".

Even though it makes the development slower (*) and quite some times boring it gives back in almost absence of uncertainty and because of repetitive patterns also ease on going back to work on a new/old part/feature.

(*) Because of planning and organisation of the code flows and layers flows, but also compartmentalization of actions (a bad example would be the mix of validation code with CRUD code)

How do you experience the separation of concern? (If you have ever had the chance)

Ps: still earning ~1400€/m, am I worth more? 🤔
