Ask HN: What does a C++ fullstack mean to you?

Recently I was contacted by a recruiter on LinkedIn who asked if I was open to a C++ job.

These are his words "I wanted to send a quick message to see if you or anyone you know might be interested in a Direct Hire full stack C++ job"

Doesn't fullstack mean having experience in different domains like frontend, backend, machine learning, data mining, mobile dev, operations etc. ?
