About
It started with old machines at my parents' grocery distribution warehouse: an Acer laptop running Windows XP and a dusty desktop with Windows Server 2003. They were not powerful, but for me they were an endless puzzle. I spent a lot of time trying to understand what was happening behind the screen, and that curiosity never really went away.
That interest eventually evolved into a degree. Today I am studying computer engineering while building projects around software and cybersecurity. I am still a student, and I do not try to hide that. What this portfolio is meant to show is how I think, how I learn, and the kind of technical work I want to keep growing into.
