// ABOUT ME
My journey in programming started early—very early. At age 7, I got my first computer, a Commodore 64, and discovered QBASIC. That moment changed everything.
Since then, I've spent my entire life coding. Not because I had to, but because I wanted to. Programming isn't just my profession—it's who I am.
Every project, every line of code, every debugging session is a labor of love. This site is where I share my journey, my projects, and my passion.
