About

Hello, and thanks for stopping by.

I’m Ruoyu, an engineer specializing in the intersection of cyber security and software engineering. I’m passionate about solving technical problems, from building secure systems to writing clean, high-quality code. My motivation comes from curiosity, collaboration, and the belief that secure software can be both powerful and elegant. Currently, I am pursuing a Master of Computing in Infocomm Security at the National University of Singapore, where I focus on topics such as systems security, cryptography, and secure software design.

In my free time, I am an active open-source contributor. A substantial part of my work involves maintaining Homebrew, the widely used package manager for macOS and Linux, as its Lead Maintainer. If you’ve ever installed software using brew, chances are you’ve already used something I’ve developed or helped maintain. You can also find my name in the output of man brew | grep Ruoyu.
