I'm aiming to become a backend engineer, but a web developer told me that I should first become a full-stack developer because employers increasingly want generalists who can work across the entire application. Is it better to take a full-stack course and then specialize in backend, or should I focus on backend development from the beginning? I'd like to understand how much frontend knowledge a backend engineer realistically needs and whether learning both sides would improve my job prospects.

Backend specialization is completely valid—there’s plenty of work building APIs, databases, services, and infrastructure. Just remember that backend systems don’t operate in isolation. Learn enough frontend to understand how requests are made, how data is consumed, and how to debug problems that cross the client-server boundary. You can specialize in backend without treating frontend as a complete mystery.
