whoami

I build things I imagine and things I need.

My interests sit at the intersection of cybersecurity, systems engineering, and backend development. I like understanding what happens underneath the abstractions: how software interacts with the operating system, how data is indexed and retrieved, how networks communicate, and how systems fail.

Build it. Break it. Understand it. Rebuild it.
