I’ve always loved learning new technologies, frameworks, and programming languages. But once, during an interview, an experienced developer asked me:
You want to learn .NET, but how deeply do you know backend development with JS?
That question made me stop and think. In our world, it often feels like the more technologies you know, the better. But if you spread yourself too thin, you risk staying at the level of “knowing a little about everything” and never becoming an expert in any one area.
Since then, I focused on my stack. I’ve realized that deep knowledge of the tools you work with is much more beneficial than a superficial understanding of a wide range of technologies.
Deep knowledge of your stack is the true path to becoming a Senior developer. Here’s why:
-
You don’t just write code, you understand how it works internally - You know best practices and can optimize projects
- You become a valuable specialist, not someone who “knows a little about everything”
- And, it’s easier to pass interviews because you don’t answer “superficially”
Think about it: How deep is your understanding of your stack? Do you really have an expert-level understanding of the tools you use every day, or are you just scratching the surface? Maybe instead of jumping to learn something new, you should dive deeper into what you already use daily?
