I'd argue that there are genuine full stack developers.
Not all companies have the budget or "perceivable" need for teams of people.
I know an e-commerce company turning over £3 million a year with a single developer who handles the design mock-ups, frontend, backend, database, backups, you name it. I'd say that qualifies as full stack.
The trouble comes when you expect a Jack of all trades to be a master in a specific field.
And I think that’s why the term doesn’t fit in my mind. There is that expectation. But you’re correct that there are absolutely people working all across the stack and doing great work. But I’d still call them stack agnostic :)
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.
