The Engineer Behind the Code

I'm a Computer Science student who thinks in algorithms and builds in systems. Before touching a framework, I make sure the logic is optimal.

I've grinded 350+ DSA problems on LeetCode & GeeksForGeeks — not just for interviews, but because algorithmic thinking makes every solution better.

ML is a powerful tool in my engineering toolbox. My foundation is C++, data structures, systems thinking, and writing code that actually scales.
