Learning systems by building, testing, and documenting them.

Understanding systems by working with them

I'm an IT student interested in understanding how computer systems work. My main areas of interest are networking, cybersecurity, Linux, and server administration.

Most of what I learn comes from hands-on work: building small labs, configuring systems, testing ideas, investigating problems, and documenting the results.

I'm still learning, and that's intentional. This website is a record of that process.
