Systems first.
Tools second.

I am a Computer Science student who is most interested in how applications actually run: networking, Linux, containers, cloud infrastructure and automation. I prefer understanding the system behind a tool and being able to explain why a configuration works, rather than only knowing the command to run.

My current internship focus is cloud / DevOps, network / infrastructure and cloud security.
