A bit off-topic: is only my experience or usually full stack developers are paid less than a frontend/backend engineer ? seems like full stack developers are seen as generalist and so paid less.
I am observing that I am getting much more opportunities once I have changed my role from full stack to front end developer. I think recruiters want experts in one field rather than generalists.
Smaller teams find more value and flexibility in generalists, whereas larger teams are more likely to want specialists. Larger teams typically belong to larger companies, which have more resources and offer higher salaries than your typical startup.
