What skills outside your main programming language help you stand out?

Get comfortable investigating things from the terminal. Searching and filtering logs, combining command-line tools, and using regular expressions can make it much quicker to narrow down a problem.

You don't need to switch editors or memorize every command. Pick a recurring task, like finding related errors across service logs, and learn a better way to do that first.

Systems thinking is a big one for service work. Learn how requests move between components, where state lives, and what happens when a dependency is slow or unavailable. That gives you a better frame for troubleshooting than looking at one function in isolation.

Distributed systems concepts are worth studying too, especially when you support the services and pipelines around your code.

Writing and communication. A clear explanation of a technical decision or a respectful conversation when people disagree can help a team make progress. Empathy matters here too, because the best explanation depends on what the other person needs to understand.

Learn how to find things out. Good searches, reading documentation, and checking whether an answer actually applies to your problem will take you further than knowing a particular editor. Tools change, but the habit of investigating carries over.

Security is a useful direction if you want something technical beyond the stack. Learning how common attacks work can change how you think about the services you build and support. Hands-on security exercises are one way to explore it.
