I'm aiming to become a backend engineer, but a web developer told me that I should first become a full-stack engineer because employers increasingly want generalists who understand the entire application. Is it worth taking a full-stack course and learning frontend development, or would it be better to focus directly on backend skills instead of spending time on areas I may not use?

The safest approach is to become specialized with some breadth. Employers generally like backend developers who can understand the whole application and collaborate across layers, but that doesn’t mean everyone needs to be equally skilled at everything. Choose backend technologies you want to work with, build a couple of complete projects, and add enough frontend knowledge to demonstrate how your services are used.
A lot of companies do advertise full-stack roles, but many of those jobs are really backend-heavy—something like 80% backend and 20% frontend. Learning enough frontend to understand how the pieces connect can make you more employable, while you can still make backend your main focus.
You don’t have to force yourself into frontend development if you genuinely dislike it. There are backend-focused paths in areas like data engineering, APIs, infrastructure, and distributed systems. Just be clear that a job advertised as full-stack may involve a significant amount of frontend work, so check the actual responsibilities carefully.
I’d recommend building a strong backend foundation first, then learning the frontend basics afterward. You should understand how browsers, forms, HTTP requests, authentication, and a frontend client interact with your API, but you don’t need to become an expert at designing interfaces or mastering every frontend framework.
Full-stack expectations aren’t entirely new, and they vary a lot by company. Smaller teams may expect one person to handle nearly everything, while larger or more specialized teams may hire dedicated backend engineers. Don’t choose a course just because the label sounds more marketable—look at job postings in your target area and compare the skills they actually request.
Even when companies expect engineers to understand the full stack, that usually means being able to work with and communicate about the other layers—not necessarily being an expert frontend developer. Specialized roles still exist, especially in data and infrastructure.
