Before I answer, I need to give some background. I’ve been in IT for past 20 years. I’ve been a backend developer, frontend developer, mobile developer, database administrator and most recently a devops engineer. I’ve got a degree in electronics and telecommunications and have had quite a bit of exposure to printed circuit board design, including processor programming. To answer your question, when someone refers to me as a “full stack” I don’t take this as an insult. But it’s diminishing.
