> My Passion for Computer Science

My Passion for Computer Science

Introduced early to the IT world by my sister, an industry professional, I quickly grew deeply curious about technology.

My fascination with coding truly sparked at the end of middle school when I built my first web pages. What started as a hobby evolved into a true calling as I tackled algorithmic logic through Python and Java.

This constant drive to build and solve complex problems is what inspires me today to pursue a career in software development.
