SYSTEM ONLINE · 2026

Hi, I'm Rafa.
I connect systems, ideas, and interfaces.

SMK TKJ graduate now pursuing a Bachelor's in Informatics. I work on computers from the inside out—hardware, networks, and the troubleshooting in between.

01 / PROFILE

A few signals
from my feed.

My TKJ background taught me to think in systems: what lives beneath the case, how devices connect, and how to isolate a fault. Now in Informatics, I’m expanding that hands-on foundation through code, data, and software.

02 / WHAT I DO

Hands on with
the machine.

Not just theory, I like opening the case, following the cable, reading the logs, and getting the system back on its feet.
