Yes, but tell that to the job market. Apparently, at least in EU, it's very trendy to pay full-stacks less money than those who are specialized in either front-end or back-end only. It's unfortunate.
Because the businesses wanting "full stacks" are cheap and view thier tech as an overhead/commodity. For some reason people are willing to work for them. If I am building the back end I would laugh and walk off if you started going on about me touching the front end. It's like hiring a data scientist and then forcing them to do the data engineering work also. Rediculous and hoaky.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
