I've worked with very few developers that I could even begin to call full-stack. They either segment themselves as front-end or back-end only, and can't cross the divide. I don't much like it, because that interface between the two is usually terrible as a result, with pieces that don't match, APIs that don't even work, and generally a huge amount of work to integrate by somebody that actually understands both pieces, that rivals rewriting it completely. Owning an entire vertical slice is so much easier, and produces a better quality product.
