Oh sorry, I am a developer but I forgot to take into account the cost of living too, in my country the minimum salary for a junior developer is 400 dollars, taking into account the cost of living, only the rent and basic services cover almost 3 / 4 of the salary. I don't know how the cost of living in the Netherlands will be, but in my country it is very expensive.
How do you earn so much money? I didn't think that starting a startup brought you so much money. Of course, getting clients is not an easy task, but at the same time, I see that they are the businesses that attract more customers.
